Amritsar Police on Thursday arrested Shiromani Akali Dal leader Ranjit Singh Rana and an accomplice on charges of killing Assistant Sub-Inspector Ravinder Pal Singh after he had objected to them harassing his daughter.
Police Commissioner Ram Singh said Rana was arrested from the border belt of Amritsar district on Thursday morning along with another accused.
Rana had been stalking Ravinder Pal Singh's daughter for the last few days. Two other accused in the killing of Ravinder Pal are absconding.
The incident took place on Wednesday afternoon near the Chhehrata police station, which is on the outskirts of Amritsar city, 250 km from Chandigarh.
Ravinder Pal's daughter had complained that some youth used to harass her. The ASI objected to this and confronted the youth. Following an argument, Rana fired at him and his daughter and left them injured.
Witnesses said Rana and his accomplices came back to the spot in a jeep later and shot Ravinder Pal Singh in the chest from close range.
The latter was rushed to a private hospital where he was declared dead.
The Akali Dal expelled Rana, who is a general secretary of the district unit of the party. (ANI)
