Rammy Lopez, 32, of Brooklyn, allegedly whacked a 7-year-old boy as he walked with his 3-year-old sister and babysitter on a day off from school, around 12:30 p.m. Wednesday, according to his mom, who declined to give her name. 

The teen was on her way to Baychester Middle School around 8:20 a.m. when the perv approached and dragged her into a secluded area at East 233rd Street and Wilder Avenue in Edenwald – around the corner from her school, authorities and sources said. 

"He just kept punching me and punching me and punching me and punching me."

The victim – who did not want his name used – had just finished work and was walking at the corner of Eighth Avenue and West 49th Street, bound for the Port Authority Bus Terminal, around 8:45 p.m. when the attacker approached and knifed him without warning.

Jamel McGriff also pawned off the couple's two cellphones at a Bronx check cashing store using his own personal identification for the transactions.
