Shasta County Sheriff's bomb squad is handling sensitive explosive material after a man in Redding blew off his own hand Thursday.

Bomb technicians found 40 pounds of explosives at the home of 63-year-old D. Ray East.

Sheriff Tom Bosenko says some of the materials are considered so unstable, deputies have not been able to enter the home. He says the slightest touch could cause them to detonate.

Despite the large amount of explosives, Bosenko says there is no evidence suggesting terrorist activity.
