Cops seized a stash of guns — including an AR-15 — from a Houston hotel room Sunday, officials said.

Police were called to the Hyatt Regency Houston to help deal with Russell Ziemba after the drunken guest allegedly got into a confrontation with an off-duty cop.

A search of Ziemba’s room uncovered the AR-15 semiautomatic weapon, a shotgun, a handgun and ammo, authorities said.

Ziemba, 49, reportedly told cops he was at the hotel to celebrate New Year’s Eve and brought the weapons so they wouldn’t get stolen.

Houston police said they didn’t believe he intended to use them unlawfully.

Ziemba was charged with assaulting a peace officer and trespassing.

The hotel’s New Year’s Eve bash is one of the city’s largest parties. About 2,000 people attended.
