The Poojappura police have taken a man into custody on the charge of murdering his father-in-law and brother-in-law.

The accused Arun, 31, of Muttathara, who was drunk stabbed them with a knife, the police said. Though the grievously injured Sunil and Akhil were taken to Government Medical College Hospital, they could not be saved.
