Fifteen people have been detained by Delhi Police in connection with the gun-battle that left liquor baron Ponty Chadha and his estranged brother dead at a farmhouse here a day ago, police said Sunday.
"We are questioning 15 people who were present in the farmhouse during the bloody gun battle. We are trying to piece together the sequence of events," a police official said.
Police is trying to find out why only the warring brothers -- Ponty Chadha and Hardeep Chadha -- were killed, when the shootout was between their groups at a farmhouse in Chattarpur Saturday.
The postmortem report of the bodies is yet to come.
