AMRITSAR: Punjab Police on Tuesday registered a case against Finance Minister and Congress candidate for the Amritsar Lok Sabha seat Surinder Singla for slapping an election official outside a booth in Majitha town.

The keenly contested by-election between Singla and Bharatiya Janata Party's (BJP) Navjot Singh Sidhu is being held along with assembly elections in the state on Tuesday.
