The Florida teen busted Wednesday at the Port Authority Bus Terminal for threatening to kill a cop is wanted in his home state for a multiple shooting last month, sources said.

Hunter Lee Taylor, 18, allegedly fired into a crowd in Groveland, Fla., on June 27 and wounded at least two people.

Taylor was arrested on Wednesday after allegedly telling a homeless man with whom he was smoking pot that he wanted to kill a PA cop who was passing by.

After making the threat, Taylor pulled out his holstered .38-caliber revolver, the sources said.

The vagrant, George Pugh, 46, reported Taylor’s plan to cops, prompting Taylor’s arrest. He was set to face arraignment on Thursday.
