Back when we had a real job, whenever computer equipment turned up missing at the office, we figured it was one of the mailroom guys. But it appears there are independent operators who go hither and thither stealing laptops and other electronics out of midtown businesses. Here’s one who pulled a spree back in May and June –hitting no fewer than ten separate offices between 28th and 57th Street, mostly around Fifth Avenue — and then returned for encores on October 23 at 44 East 30th Street and 432 Park Ave South. He usually does his work while wearing a business suit and a baseball cap — a Yankees cap last time, which certainly would have helped him blend in — and is believed to be 30-40 years old, 5’9″-6’0″, and bald with some facial hair. Any info? NYPD asks you to contact 1-800-577-TIPS(8477), www.nypdcrimestoppers.com, or text 274637 (CRIMES), then enter TIP577.
