Super perv stripped of apt. keys

An Upper West Side super no longer has the keys to apartments in the buildings where he works — after The Post exposed his child-molesting past and accusations by tenants that he tried to shake them down for sex.

The landlord of those buildings, Stanley Katz, is “evaluating what he’s going to do” about his super, Level 3 sex offender William Barnason, said Katz’s lawyer, Santo Golino.

“Billy has no access to the keys,” Golino said.

Despite having served 14 years in prison for rape, sodomy and sex abuse involving three young Long Island girls, Barnason has for eight years worked as a super for Katz, with access to the keys for about 50 units in three buildings on West 73rd and 75th streets.

Several female tenants of those buildings said the 57-year-old propositioned them for sex by suggesting he would help them with or waive their rent, which he collects for Katz.
