A man proposed in Times Square. Moments later, his romantic plan went horribly wrong.

Police are looking for a couple who lost an engagement ring down a grate in New York moments before the man was due to propose.

The New York Police Department said the man had got down on one knee on Friday night and was so excited when she said yes that he dropped the ring.

It fell about 2.4 metres, police said.

Officers have since recovered the ring – and cleaned it – but the would-be bride and groom left without passing on their names or any contact information.
