Several purported videos of the driver, identified as Mohammad Aamir, being thrashed by 2-3 men with belts while his shirt had been ripped off, surfaced on social media on Monday night.
SP (City) M.P. Singh said that the van, which was heading to Sikandrarao in Hathras from Mathura's Govardhan, was intercepted by local residents and cow vigilantes from a right-wing outfit in Raal village.
However, during the preliminary investigation, nothing, except some animal carcasses for which Aamir had a licence, was found in the van, Singh said.
Two other men were also beaten up by the public over suspicion of their links with the van driver, said the SP, adding that they rescued all the three men from the mob and sent them for medical treatment.
According to doctors, Aamir had received bruises on his face and shoulder. "He did not suffer any major injuries," doctors said.
The SP (City) further said that two FIRs have been registered in the matter.
