Cops overlook handgun in turnstile jumper’s
waistband 1

Cops brought an accused turnstile jumper all the way to a police station — and marched him in front of a desk sergeant — before realizing the man was packing a handgun in his waistband, The Post has learned.

Ex-con Billy Walters, 37, walked through an emergency subway gate at the 149th Street station without paying the fare around 11:45 a.m. Tuesday.

Cops took him to Transit District 11 near Yankee Stadium but didn’t discover the .45-caliber Sig Sauer in his waistband until they got him in front of the station’s desk sergeant, according to a source and photo obtained by The Post.

The NYPD patrol guide states that a frisk should be conducted as soon as a person is taken into custody — with special attention given to the waistband.

Walters, who is homeless, was charged with criminal possession of a weapon and menacing, cops said.

NYPD officials did not immediately return a request for comment on the oversight.
