Malad police station has formed three special teams to trace the accused while equal number of squads have been constituted to crack the case by crime branch, police said.
Additional Police Commissioner Kishore Jadhav said, "We identified the accused and are trying to trace him."
Shagufta Khan, the wife of a bookie, who had been arrested in a betting case some years ago, was found murdered yesterday afternoon at her residence in Rustomjee apartments at Marve Road in suburban Malad, police said.
The accused had slit the throat of the victim with a knife before running away with cash and gold valuables. As the culprit was about to sneak out of the house, the victim's two minor daughters entered home. The accused also tried to attack them with the knife, but children managed to save themselves.
"Since yesterday, family members of the accused and the owner of the premises rented out to run the mobile shop by the culprit were questioned, but in vain," said a crime branch officer.
