A slick thief skated right into the National Hockey League’s Midtown headquarters during business hours and darted off with a top exec’s laptop computer, cops said Wednesday.

The robber got into the NHL’s 14th-floor offices at 1185 Sixth Ave. at West 47th Street on Sept. 10 at about 1:50 p.m., law-enforcement sources said.

He scored the laptop belonging to Jamey Horan, the league’s vice president of communications.

Horan, who could not be immediately reached for comment Wednesday, is one of NHL’s more visible executives, frequently ­going before the cameras to announce ­major initiatives, such as ­details about the league’s popular annual outdoor-game series.

The burglar is balding, approximately 5-foot-9 and between 35 and 40 years old.

He was last seen wearing a red T-shirt, black athletic shorts and black shoes with white shoelaces.

The sources say the suspect is also believed to have stolen a laptop from a Midtown hair salon on Sept. 5.

He slipped into Alterna Haircare at 551 Fifth Ave. and fled with the computer.
