The call for modifying an ancient law grew louder, as several discotheque owners met Home Minister RR Patil on Tuesday with a request to alter the overcrowding law that prohibits more than 10 couples on the dance floor. Recently, cops under the pretext of precautionary measures penalised dozens of pub and discotheques in the city for overcrowding the premises, which they claimed might lead to a stampede in case of an emergency. According to pub owners, the Social Service Branch (SSB) of Mumbai police have been cashing in on this age-old rule by fining owners several thousand rupees, if they are found violating the order.
