Curfew was imposed in parts of this Punjab city as hundreds of migrants went on a rampage yesterday, burning several vehicles and blocking the highway and railway tracks to protest police inaction against an alleged gang of bikers looting them for the past few months.

The Ludhiana-Delhi National Highway No 1u00a0 was blocked due to the violence.

Railway traffic was also affected as nearly six trains were held up at various stations due to violence and blockade on railway tracks by the mob in Ludhiana.

Under Control: Police had to lathicharge the mob yesterday.

Police used tear gas, cane charge and firing in the air to disperse the rampaging mobs.

Punjab's Additional Director General of Police (Law and Order) J P Birdi said, "Violence has broken out in the area. The mob has set several vehicles on fire.

I am myself reaching the spot. Police reinforcements and officials are on the spot to control the situation."

District cops were unavailable for comment.
