Apple products have been a big hit with New York's thieves this year.
Police have seen a 40% increase in thefts involving the company's phones, computers, tablets and music players so far this year, the NYPD said Monday with at least 11,447 incidents as of Sunday, a jump of 3,280 over the same period last year.
In comparison, the number of overall crimes in the city has gone up by about 4%, the department said, with just over 3,000 extra crimes through Sunday.
"Individuals alert to their surroundings are less likely to become victims of thefts of iPhones and other handheld devices," Police Commissioner Ray Kelly said in a statement Monday night.
Apple did not return requests for comment Monday night.
The NYPD has been trying to educate New Yorkers to keep their electronics in a safe place, register them with the department and to download apps that can track down a phone's location if it's stolen.
Over the weekend, the NYPD registered iPhones at 21 stores in the city.
Cops have also been targeting subways to catch would-be crooks, who often try to swipe Apple products from sleeping straphangers.
The NYPD began sending officers on every weekend overnight subway in the Bronx and No. 7 and A trains in Queens this summer, transit bureau chief Joseph Fox told MTA officials in July.
