HARTFORD, Conn. (AP) — Authorities say the public pool where a 16-year-old Connecticut boy drowned during an illegal after-hours swim had a video surveillance system meant to detect trespassers, but it was broken.

Hartford Mayor Luke Bronin says the surveillance system broke sometime during the recent heatwave and city officials knew it was not functioning.

He says had it been working, it may have alerted police to trespassers at the pool.

The victim was among as many as 20 youths who scaled the 10-foot fence at Keney Park pool after it closed Tuesday evening then later scattered. The boy was reported missing at about 1 a.m. Wednesday and found in the pool about an hour later. City officials have not released his name.

Bronin says the surveillance system has since been repaired.
