Four men were arrested Friday on charges of rioting and assaulting police personnel after a scuffle at a Chinese smartphone manufacturing facility, police said. On Thursday, over a thousand workers of the Hipad Technology India, which assembles and tests Xiaomi phones, restored to violence after around 200 of them were allegedly sacked without notice. Apparently peeved over the situation, the workers went on a rampage at around 10 am, pelting stones at the building and barging into the facility in Sector 63.

"Four workers have been arrested for the violence, throwing stones and damaging the office. They have also been booked for indecent behaviour and scuffling with police officials and obstructing them in the duty," Station House Officer (SHO), Phase 3, Akhilesh Tripathi said. He said there was no complaint from either side but the police had taken suo motu cognisance because the incident had caused a law and order situation in the vicinity. Those arrested were identified as Yogesh Kumar, Akhilesh Kumar, Deepak Pandey and Yogesh Pal - all under 30 years of age, he said. They were booked under Indian Penal Code sections 147 (rioting), 332 (voluntarily causing hurt to deter public servant from his duty), 353 (assault or criminal force to deter public servant from discharge of his duty) and related offences, the SHO said.
