Casper police arrested a Casper man on Thursday night who is suspected of assaulting his girlfriend with a large brass ashtray.

Michael Grant Harmon, 36, was booked into jail on suspicion of assault and battery, methamphetamine possession, carrying a concealed weapon and interference with a police officer after an officer chased him down and used a Taser on him.

An officer, looking for the suspect, saw Harmon walking in the 1000 block of Burlington Street about 11 p.m Thursday. Harmon began running when he saw the officer and didn't stop until the officer fired his Taser at Harmon, striking him in back, according to the affidavit.

Harmon fell to the ground, the affidavit stated, but the police officer had to fire the Taser a second time after Harmon refused several times to comply with the officer's requests.

The officer found a sheathed 4.5-inch, fixed-blade knife in the backpack Harmon was carrying, the affidavit said.

After returning to his car, the officer received a call from the girlfriend's son alleging Harmon had just hit his mother.

The girlfriend said Harmon struck her right arm with the brass ashtray, pushed her against the wall and choked her with a squeegee handle, according to the affidavit.

The affidavit also said Harmon's girlfriend had injuries to her neck, collar bone and right arm.

After arriving at the police station, a Natrona County sheriff's deputy found a small bag of meth on Harmon, the affidavit alleged.
