CCTV pictures have been released of three men police want to trace following an assault on a taxi driver.
The attack happened after the driver confronted passengers who ran off without paying their fare.
It happened near to the Bootleggers pub in Wellingborough Road, Northampton, shortly before 5am on Sunday after three men had caught a taxi from Aspers Casino.
After the three men got out of the taxi and ran off without paying, the driver got out and chased the men.
The driver managed to pick up a mobile phone one of the men dropped and told him he would get it back when the police arrived.
However, the men attacked the driver and one of them hit him with a weapon, causing him to fall to the ground.
The men continued to kick the victim and one of them went through his pockets and stole his phone and cash, while another went back to the taxi and stole the PDA dispatch radio system.
The three men then ran off. They are described white, aged between 24 and 30 years old, of muscular build and about six foot.
The first man was head and wore a white v-neck top. The second had short brown hair and wore a grey top. The third had short brown hair and wore a dark patterned top.
