Live tear gas grenade discovered by scuba diver in Oklahoma lake.

A scuba diver exploring Lake Murray in Oklahoma found a live CS gas grenade, which was confirmed by the authorities. The Oklahoma Highway Patrol's bomb squad safely collected the grenade and will detonate it at an offsite location. The grenade was identified as an M7A3 Riot CS, a riot control hand grenade used for tactical missions. It is unclear how the grenade ended up in the lake. The scuba diver was applauded for contacting authorities about the find, and others were encouraged to do the same.
