Preliminary information indicated two males and two females were wounded in the shooting, Hartford police Lt. Paul Cicero told The Associated Press. The fatality was a 28-year-old man, a tweet from Hartford police said.

Two of the wounded were still in surgery as of 7:30 a.m., the tweet said, while two others were “stable.” Their exact conditions and the extent of their injuries weren’t released.

Further details, including information about the shooter, weren’t immediately available. Police closed streets in a one-block radius surrounding the club for some time.
