A man accused of being a walking drug emporium — allegedly carrying cocaine, crack, heroin and pot — was still on the lam Saturday, a day after he walked barefoot out of a Harlem police station.

Arthur Collins, 57, was busted Friday afternoon when cops got a 911 tip that he was lurking inside an apartment building on Madison Avenue near 126th Street, according to police.

Cops arrested Collins after a brief chase and said he possessed the drugs as well as a firearm silencer.

They took him to the 25th Precinct on 119th Street for processing and left him in a holding cell. He was reported missing when cops went to check on him.

Cops were seen standing outside the precinct station house on Friday night, pointing at an open first-floor window.

Collins was last seen wearing black jeans and a black shirt — and no shoes.

He wasn’t the first recent suspect to give cops the slip.

A slippery attempted-murder suspect, Tareek Arnold, 23, who fled from officers while handcuffed near the 32nd Precinct last month, was recaptured Monday night.
