TAMPA, Fla. (AP) — A fourth teen has been arrested in the brutal beating of a U.S. Army sergeant on a Tampa street earlier this month.

Tampa police said 18-year-old Brandon Miller turned himself in after an arrest warrant was issued last week. Police said that Miller was uncooperative and showed no remorse when he was booked into the jail Tuesday.

The mugging of 24-year-old Johnny Aparicio gained national attention when security-camera footage of him being punched and kicked in the May 13 incident was released to the media. Police subsequently arrested three teens and charged them with aggravated battery and robbery.

Miller was being held on $50,000 bail. Jail records don’t list an attorney.

Aparicio, who sustained facial injuries, is recovering.
