Police have released footage of three men they want to speak to after a man was injured in an armed robbery in Erith.

The victim had to be taken to hospital after he was slashed with a weapon and had his possessions snatched from him.

A video shows two men running past a CCTV camera while another man appears in the front of the shot, looking over his shoulder.

The second shot shows two men dressed in black walking down the street.

According to police, the robbery happened on Tuesday, March 20 in the afternoon.

They explained there was a delay in uploading footage while other lines of enquiry were followed.

However, officers have now said they need to identify the men in the video.

Anyone who might know any of the men in the footage is urged to call Crimestoppers on 0800 555 111 quoting image refs 007973, 007975 and 007976.
