A mob vandalised a police station in Trombay area in the wee hours yesterday, after the police arrested a person for 'hurting religious sentiments' through a Facebook post the previous night.
The mob wanted the police to hand him over to it. In a fit of rage, it attacked the police station and torched some police vehicles.
Police arrested 17 persons for rioting.
Today another seven persons who were allegedly part of the mob were arrested, a senior police official said here.
