One of the two suspects arrested Friday in connection with a violent attack on a U.S. serviceman is a Robinson High School student.

Geroshe Lewis, 18, of 4712 W. Wallcraft Ave., was arrested Thursday afternoon at Robinson as school ended for the day, Tampa Police reported. Also arrested Thursday was Lerome Howard, 18, of 8013 N. 13th St.

Both men are charged with robbery and aggravated battery after police say they were seen on camera attacking U.S. Army Sgt. Johnny Aparicio, 24, around 3:30 a.m. Sunday on Iowa Avenue in South Tampa.

Investigators are still looking for two other men also seen punching and kicking Aparacio on the video footage.

A reward totaling more than $16,000 has been posted by a law firm, a local church and two private citizens for information leading to arrests. Detectives said they have received dozens of tips throughout the week with potential suspect names, some of which helped lead to Friday's arrests.

"The same names were consistent in many of the calls," a Tampa Police spokesperson wrote in a news release.

It was not immediately clear how much reward money might be issued as a result of Friday's arrests.

Lewis is a senior at Robinson High and didn't belong to any clubs or play any sports, Hillsborough County School District spokesperson Steve Hegarty said. Lewis is not in the school yearbook.

"Based on the charges and the seriousness of the alleged crimes, he will not be returning to Robinson High School," Hegarty said.

Lewis and Howard were to be booked into Orient Road Jail, officials said.

Aparicio, who is assigned to U.S. Central Command at MacDill Air Force Base, is recovering from his injuries, according to Tampa Police. He was released from the hospital Wednesday.
