Eleven people drowned when two boats carrying them capsized during the immersion of a Ganesh idol in Lower Lake of Bhopal, a senior police official said on Friday.

The incident took place on the intervening night of Thursday and Friday in Khatlapura on the banks of Lower Lake, deputy inspector general of police Irshad Wali told PTI.

Eleven people died in the incident while six were rescued, Bhopal collector Tarun Kumar Pithode said.

A magisterial probe has been ordered into the incident, Pithode said.

A total of 17 people were going on two separate boats for the immersion of the Ganesh idol at Khatlapura ghat when the incident took place at around 4.30 am, the collector told PTI.

Initially, the first boat tilted and when the people on the other one saw it, they tried to save it, but it was to no avail. In the process, the other boat also tilted sideways and both capsized, an official said.
