A MAN who suffered "serious knife wounds" in an attack following a night out in Essex may have had his hand cut off, the BBC understands.
Police are questioning a man on suspicion of attempted murder following the attack in the High Road in Loughton at 23:30 GMT on Friday.
The victim in his 20s suffered wounds which left him in a "life-changing condition", a police spokeswoman said.
A large knife was found by officers at the scene, the force said.
The victim had been on a night out with a group of friends but was then attacked in the street "by a group of three or four men", the spokeswoman added.
A group is believed to have left the area in a black Audi A8 which was later found on fire in Waltham Abbey.
One of the suspects, a 30-year-old man from Grays, was arrested after being chased by a PCSO on foot.
"Officers do not believe that this was a random incident and it may have been a targeted attack," the force added.
