HAUPPAUGE - A Hauppauge hotel reopened today after a small electrical explosion injured three people.

Emergency crews were called to the Hyatt Regency in Hauppauge just before 5 p.m. on Monday.

Fire officials say an engineer was working on an electrical panel when a fuse short-circuited.

That engineer and two other workers were burned in the small explosion. One remains in critical condition.

The Hyatt was closed yesterday, with guests being re-located to a nearby hotel.
