Monday's news in under 5 minutes.

UPDATE: Air Chief Marshal Angus Houston says authorities are investigating the “most promising lead” so far in relation to flight MH370.

But Houston has warned it could take days to confirm whether the new lead — signals picked up by the Australian navy ship Ocean Shield — is indeed linked to the missing plane, the BBC reports.

“I would ask all of you to treat this information cautiously and responsibly. … We haven’t found the aircraft yet,” Houston said.

Acting Transportation Minister Hishammuddin Hussein said Malaysian authorites were hopeful there will be a positive development in the next few days or even hours.

But time could be running out in tracing the sounds, CNN reports.

The batteries inside the plane beacons, designed to start sending signals when a plane crashes into water, last around 30 days after the devices are activated — and today marks the 31st day of the search.

UPDATE: Benjamin Milward, the man wanted for questioning over the murder of French Student Sophie Collombet, has reportedly been arrested in Coffs Harbour, NSW, after he was seen in a supermarket.

Last weekend QLD Detectives released CCTV footage of the 25-year-old man boarding a train at South Brisbane at 11.23pm on the night Sophie Collombet was murdered.

More to come.

1. Sophie Collombet murder

The police believe that the man wanted for questioning over the murder of French student Sophie Collombet had consumed drugs – possibly even ice – and alcohol.

Over the weekend, QLD Detectives released CCTV footage of the man, 25-year-old Benjamin James Milward, boarding a train at South Brisbane at 11.23pm on the night Sophie Collombet was murdered.

The French student was assaulted around 9pm on Thursday, March 27, near the William Jolly Bridge. Her naked body was found at 6am the next day.

2. Search for MH370

Three separate ‘pings’ have been detected in the search for missing jet MH370.

Air Chief Marshall Angus Houston confirmed that a Chinese ship had picked up electronic pulsing signals twice in a small patch of the search zone, once on Friday and again on Saturday.

On Sunday, an Australian ship picked up a third signal in a different part of the massive search area.

A British navy ship HMS Echo, which is fitted with sophisticated sound-locating equipment, is expected to arrive in the area this morning.

Meanwhile, CNN has reported the plane may have flown around Indonesian airspace in what may have been a deliberate attempt to avoid radar detection.

4. The new WA Senate

Sixty-eight per cent of the vote has been counted in the new WA Senate vote from Saturday.

The Greens’ Scott Ludlam and the Palmer United Party’s Dio Wang both claimed a seat.

6. Judge grants mother right to flee

A Melbourne judge has granted a young domestic abuse victim the right to leave the country with her infant son.

The court heard claims that the man had expressed extreme jealousy towards the woman installing tracking devices on her phone, testing her underwear for semen and at one stage choking her “to see the light fade from her eyes”.

The woman had applied for sole custody and permission to move back to her homeland.

Judge Judith Small found the man had subjected his former partner to a “persistent regime of domestic terrorism”, and allowed the woman to leave.

7. Travel company demands proof wife is dead

The husband of shark victim Christine Armstrong has spoken of his anger at a travel company who asked him for proof his wife was dead before they would refund his deposit.

The couple had planned a Darwin to Adelaide campervan trip. But the company requested proof that his wife had been killed before telling him in an email that his ‘‘booking deposit is non-refundable”.

8. Plan to collect uni debts from the dead

A report from the Grattan Institute has shown that the government could collect about $800 million a year by 2017 if it recovered HECS debts from deceased estates worth more than $100,000.

Grattan Institute Higher Education program director Andrew Norton told The Sydney Morning Herald that deceased estates would generate little income in the short-term.

“This way will bring in very little actual cash in the near future but it will have a big accounting effect on the budget,” he said.

12. Mother drowns two sons

Two young boys have died after their mother allegedly drowned them in the bathtub.

The woman, Laurel Michelle Schlemmer, in the US state of Pennsylvania held the three-year-old and the six-year-old underwater after their older brother had gone to school. She claims “voices” told her to do it.

The woman had last year backed her car into the two boys but that was ruled an accident.

She has been charged with criminal homicide and appeared in court wearing a special vest that is designed to prevent inmates from tearing off their clothes. AP reports that the mother is on suicide watch.
