A creep armed with a knife is wanted for touching himself on a Bronx bus in front of children and their mother, police said.
The 27-year-old mom asked the sicko to stop masturbating about 5:45 p.m. July 9 on the Bx2, and notified the bus driver, cops said.
The man then approached her and flashed his weapon.
She struggled with him, and grabbed the assailant’s hand to defend herself, authorities said.
When the bus stopped at E 171st Street and Grand Concourse in Mount Eden, the suspect ran off, police added.
The victim was not injured.
Police are asking anyone who can identify the suspect to call Crime Stoppers at 1.800.577.TIPS or visit www.nypdcrimestoppers.com.
