Four transit cops arrested a man who allegedly groped an 8-year-old boy on subway train, police said.
The arrest was made after a 32-year-old woman called police and told them her son was assaulted on the 7 train at the 69th Street station in Flushing on Monday, authorities said.
The mom pointed out the man to the cops, and they arrested him without incident, police said.
EMS also responded and determined the boy was not physically injured.
The suspect was arrested and charged with forcible touching, sex abuse and endangering the welfare of a child, police said.
