Authorities sealed three illegally constructed farmhouses, including one belonging to Punjabi singer Daler Mehndi, located near Damdama lake at Sohna on Tuesday, a senior official of the department of town and country planning (DTCP) said.

"These were unauthorised farmhouses in the reservoir area of the lake. All three farmhouses have been sealed. These were developed in the Aravalli range without any permission", said District Town Planner (DTP) Amit Madholia.
