The Cyberabad police on Sunday registered cases against film actor Navdeep and his friends for reportedly thrashing a group of engineering students at Madhapur on Saturday night.

Police said the actor along with his friends and some engineering students were partying at a pub at Novotel hotel in Madhapur. The students misbehaved with one of Navdeep's female friends in his absence and later left the pub.

Navdeep and his friends, however, noticed the students near an ice-cream parlour at Madhapur and picked up an argument with them. The actor's friend, Jayawardhan, grabbed the mobile phone of a student and smashed it on the floor which led to an altercation, police said.

On receiving complaints from the two groups, police registered cases against them and launched investigations.
