Detectives apprehended a suspect who strolled out of a Manhattan precinct today in front of about 100 cops gathering for a fellow officer’s funeral, The Post has learned.

The suspect, Fred Lando, 44, was being interrogated about a grand larceny case in the detective’s bureau at the First Precinct in Tribeca at around 1:30 p.m., when he somehow slipped away and waltzed out of the Ericsson Place stationhouse, sources said.

Incredibly, Lando managed to sashay unnoticed past dozens of officers gathering for the funeral of Police Officer Philip Chlanda, 29, who killed himself earlier in the week, sources added.

Lando was eventually nabbed in The Bronx

It was unclear if Lando was handcuffed or shackled.
