Maricopa County Sheriff Joe Arpaio's office said in a news release that the allegation is unfounded. Seagal said he is outraged.
Seagal and numerous deputies and posse members were present March 9 during a raid at the home of Jesus Llovera.
Llovera has filed a $25,000 claim against the sheriff's office for humiliation, emotional distress and property damage.
His claim states the sheriff's office and Seagal set off explosives to create a distraction and confusion. The claim says Seagal was free to commandeer a tank and crash through an iron gate on the southeast corner of Llovera's property in southwest Phoenix.
Seagal was participating in the raid as a special deputy sheriff for his show "Steven Seagal Lawman" on the A&E channel. His credits include "Under Siege," "Above the Law" and "Fire Down Below."
