Punjab Police chief Gaurav Yadav said local shopkeeper, Sandeep Singh Sunny, has been arrested for firing at and killing the Shiv Sena leader, while terming the incident as unfortunate.

He said a weapon of offence, a .32 bore pistol has been recovered from the possession of the accused, who runs a garment shop near Gopal Mandir in Amritsar.
