One suspect has been detained for questioning in connection with the incident, Superintendent of Police Shyam Singh said.
Suprabhat Batyabyal, who switched to the BJP from the TMC around five months ago, was not home when the miscreants broke into his house at Labhpur area in the district and kidnapped his 22-year-old daughter, according to his brother.
Before joining the TMC, Batyabal was a district committee member of the CPI(M).
"Five miscreants barged into the house around 8pm, on finding out that Suprabhat was not home.
"First, they confined us in a room and locked it from outside. Then, at gunpoint, they dragged my niece out and forced her into a car, which was parked near our home, and drove off," Sujit Batyabal said.
