The Johnny & Jugnu restaurant in Lahore, Pakistan said all 19 workers were rounded up on Friday night and kept until Saturday, the BBC reports.

In a statement, the restaurant said their staff had been repeatedly harassed by police since refusing free burgers to a group of officers.

The workers were detained for seven hours and officers were “harassing them, pushing them around, all for not giving them free burgers”.

A senior police official said nine officers had been suspended and “all of them will be punished”.
