DeWayne Alexander, 31, was remanded to the psych ward of the Metropolitan Hospital on First Avenue near 97th last weekend. On Wednesday he pushed past an attending nurse and found an unlocked door through which to flee. He’s 6′ 2″, about 200 pounds, has brown eyes, black hair, and is probably still wearing the black short-sleeved shirt with the number “3” on its right sleeve, light blue hospital pajama pants, and slip-on brown sneakers he was wearing when he bolted, and unshaven. He’s not characterized as dangerous, but he did escape from a psych ward, so look out. If you’ve seen him, NYPD asks you to contact 1-800-577-TIPS(8477), www.nypdcrimestoppers.com, or text 274637 (CRIMES), then enter TIP577.
