A customer was captured on video attacking a shopkeeper who allegedly served them fruit juice mixed with urine.

Footage shows the chaos inside the beverage stand as a middle-aged man hit a worker with his knee and fist in Uttar Pradesh on September 13.

The furious client claimed he ordered a cold citrus drink from the Khushi Juice and Shake stall, which tasted strange and smelled like ammonia.

Witnesses claimed a container was later found in the shop that had a litre of urine, but investigations on the incident are ongoing.

An officer from Indirapuri Police Station said: ‘We arrested the individuals who attacked the shopkeeper but will also question the shopkeepers.'

Officers said that Amir and Kaif, the young employees who were assaulted, were the owners of the stall. Officers said they 'provided insufficient answers during questioning' over the alleged urine in the juice.
