Police have released images of a man they want to speak to following an 'acid' attack earlier this year.

CCTV shows the individual riding a moped with a 'distinctive helmet'.

It comes following a serious assault in Keyes Road, Dartford, on Sunday February 3 where a man, was left with serious facial injuries after a noxious substance was thrown at three people.

At around 3.40pm on the day the liquid was thrown into a parked Ford Fiesta, injuring two of the occupants aged 23 and 16.

It was also thrown at a man who had stopped his car in the road to get out and help.

All three victims were taken to hospital for treatment and one of them is continuing to receive treatment for a facial injury.

Police spokesman James Walker said: "Numerous enquiries have taken place, including speaking with witnesses, gathering CCTV and checking traffic cameras. No arrests have so far been made."

The attack in February was condemned by Dartford MP Gareth Johnson who asked for harsher sentences to people found with acid, when speaking in Parliament.

Anyone with information as to the owner of the distinctive helmet or about the incident who has not yet contacted officers is asked to call police on 01474 366149 quoting 46/22668/19, or to remain anonymous Crimestoppers on 0800 555 111.
