The Punjab Police on Thursday arrested Shiromani Akali Dal (SAD) leader Ranjit Singh Rana for allegedly gunning down an assistant sub-inspector (ASI) Ravinder Pal Singh as he protested against the politician and others for harassing his daughter.
The police arrested the leader and a co-accused Gurveer Singh from Tarn Taran district of Punjab.
The police have recovered three weapons from them.
"We arrested Ranjit Singh Rana and one more person in wee hours of the day. Three weapons including 12 bore gun, .315 bore rifles and a pistol were recovered from his possession," Amritsar's Police Commissioner Ram Singh was quoted as saying by Hindustan Times.
The police said two other accused in the case are absconding.
Rana on Wednesday allegedly gunned down Singh at Chehertha area in Amritsar after the ASI asked him to stop harassing his daughter, reports said.
Singh's daughter earlier told him that Rana and his associates used to harass her.
The ASI was taken to a hospital where he was declared dead, reports said.
