PORTLAND, Maine — A Maine man injured in a pipe bomb explosion is challenging the legality of the search that found pipe bombs and 100 marijuana plants in the basement of his Alfred home.

Forty-seven-year-old Robert Infante claims the search and statements he made following a June 25 explosion should be ruled inadmissible at his upcoming trial.

Federal prosecutors say the search was legal.

Infante called 911 on June 25 to say he’d been injured in the explosion of a small propane tank. He later said he’d drive himself to the hospital. But firefighters still went to Infante’s home and found blood on a workbench, about 12 pipe bombs and the marijuana.

The Portland Press Herald says firefighters called police who were later granted warrants to search the home and Infante’s car.
