Two techies who attended a birthday party and later went inside a lake in a coracle, fell in the lake after losing balance. One swam back to safety, but the other is feared drowned.

The victim is identified as Sachin, a native of Virajpet and a resident of Electronic City, Bengaluru.

Ullas, who swam back to safety, is from RT Nagar, Bengaluru. It is said that, when the security guard at Kalkere lake, where swimming is banned, refused to allow them in, the duo gained entry illegally and took a coracle that was meant for cleaning purposes.

Ullas, who managed to swim back after tragedy struck, informed the guard and later fire and emergency personnel were called.

This morning, officials attached to National Disaster Response Force also were deployed with oxygen masks and are looking for the missing person.

Ramamurthy Nagar police have registered a case in this regard.

Preliminary reports say, the techies got drunk at a birthday party last night and entered the lake on a whim.

Following the incident, the area has been cordoned off and the walkers at the lake premises have been advised not to venture into the area due to search operations.
