Detectives investigating an assault at a nightclub in Dartford have released CCTV images of two men they would like to speak to.

A 29-year-old man needed hospital treatment after he was attacked inside the Industry bar and nightclub.

The victim went into the Spital Street venue at around midnight and noticed he was being stared at by two men.

Shortly after, they approached him and one of them is said to have punched him in the back of the head in an unprovoked assault.

The victim started to make his way out of the club and was looking to speak to security staff when he was attacked again.

This time, he was struck in the face. He was seriously injured and needed to go to hospital.

One of the men is described as being white, 6ft, stockily built, with light brown short hair. The second man was around 5ft 10ins, slim and with short dark hair. He was wearing a shirt and jeans. This man had a distinctive tattoo, with an intricate design that covered the whole of his left lower forearm.

The incident happened on September 26, but details have only just been released by police.
