MANKATO — The Mankato man arrested Saturday for detonating a pipe bomb in a neighborhood near Mankato East High School allegedly brought the explosives from another state and detonated one to celebrate the 4th of July, according the newly filed criminal complaint.
Bruce Grant, 62, is living in a group home near 229 Chatsworth Drive. Police were called at 12:10 a.m. Saturday when they received the report of a bomb threat. He allegedly lit one of the pipe bombs and rolled it down the driveway to celebrate the holiday. He turned the remaining four pipe bombs over to a staff member after he detonated the first one.

He allegedly told police he knew his actions were "wrong and dangerous."
Mankato police contacted the Bloomington Bomb Squad to dispose of the explosive devices. The investigation is still ongoing. Mankato police may filed additional information in the future.
