Six men beat up and robbed a taxi driver after he responded to a call in Northampton.
The driver was called to Danefield Road in Abington in the early hours of Saturday, July 4.
When he arrived in the road sometime between 12.45am and 1am, he was attacked by six men who stole cash, keys and his mobile phone.
Following the attack, the man was taken to Northampton General Hospital for treatment.
All of the attackers were white and skinny with short cropped hair. One was shorter than the others.
They ran away from the scene after a member of the public intervened. It is believe they fled towards Lindsay Avenue.
