POMPANO BEACH, Fla. -- A career criminal who police said exposed himself in front of two young girls on a county bus was identified because the victims recalled the suspect's most distinguishing characteristic, according to police.

Police said the incident occurred at about 8 a.m. on April 18 aboard a Broward County mass transit bus traveling in Pompano Beach.

Two girls, ages 10 and 15, were riding the bus on their way to school when police said the man unzipped his pants, exposed himself and began masturbating in front of the juveniles. He then concluded his lewd act and exited the bus at the next stop.

The girls reported the incident to authorities and recalled that the man had a tattoo of "JR" on the left side of his neck.

Investigators researched their databases and determined that 23-year-old Rudy Titus, who was participating in a Department of Corrections work release program in Pompano Beach, was identified as someone having the "JR" neck tattoo.

Police said the girls then picked Titus’ picture out of a photo lineup, and said he was the one who committed the offensive act.

Titus was taken into custody on Friday and police said he gave a statement admitting that he exposed himself to the girls.

He was charged with two felony counts of lewd or lascivious exhibition and is being held in the Broward County Sheriff's Office jail on $61,000 bond.

Police said Titus has been arrested numerous times and has been convicted on charges including grand theft, burglary and possession of cocaine.
