At least 10 people were wounded early Thursday in an apparent gang-related shooting as three gunmen opened fire on patrons leaving a nightclub in Allentown, Pennsylvania, according to police.

Allentown police Capt. Bill Lake said all the victims were expected to survive, according to The Morning Call newspaper and WFMZ.

Police arrested Angelo Luis Rivera, 20, of Allentown, on Thursday night in connection with the shooting. Rivera faces charges of criminal conspiracy to commit aggravated assault, possession of a small amount of marijuana and possession of drug paraphernalia, Lake told the newspaper.

Authorities believe there were three shooters. Police marked at least 18 shell casings on the street, The Morning Call reported.

“It appears that at least one individual was a target,” Lehigh County District Attorney Jim Martin and Allentown Police Chief Tony Alsleben said in a statement. “Although not confirmed, in our opinion based upon investigative information … it is more likely than not that the outcome of the investigation will reveal a connection to gang violence.”

The statement said witnesses and some of the shooting victims have been uncooperative with police.

Tashana Santiago, a witness who lives near the Deja Vu club, told the newspaper that many in the frightened crowd ran to a nearby shopping center as shots rang out just before 2 a.m. EST. After the last few shots were fired, Santiago said, she heard a car speeding away.

“When everything went silent all you could hear is the screaming and panicking,” Santiago told the Morning Call. “All I could think was someone is dying.”
