ANN ARBOR, Mich. (AP) — A man convicted of setting a fire that paralyzed a Detroit firefighter and injured six more has been sentenced to 15 years in federal prison.

Calvin Jones is one of two people convicted in an arson that destroyed a two-story commercial building on Detroit's east side in 2010. Firefighters were hurt when bricks and debris fell on them.

Jones' sentence was ordered Thursday by a federal judge in Ann Arbor. He claimed he was forced to participate at gunpoint by co-defendant Samson Wright, who recently received a 15-year sentence. Paralyzed firefighter Brendan Milewski told Jones that he'd be willing to serve the sentence if he could someday walk out of prison.

Wright has told authorities that he was hired to set the fire as part of an insurance scam.
