Borgesi, of the 1100 block of Durfor Street, and Ligambi, of the 1100 block of Wolf Street, were both described as employees of Ron Galati's Autobody Shop, 1118 S. 12th St.
Police said the assault stemmed from an argument over the failure of Jo Jo's to continue referring clients to Galati's.
Defense attorneys disagreed. Ligambi's attorney, Michael Pinsky, said the altercation was a "neighborhood personal dispute." Pinsky arranged the surrender of both Ligambi and Borgesi. The two were being held last night pending an arraignment and bail hearing on charges of aggravated and simple assault, terroristic threats, wreckless endangerment and conspiracy.
Joseph Santaguida, who represents Borgesi, said the incident was being blown out of proportion because of the reputations of those involved.
"It was just a fight among neighborhood kids," Santaguida said.
Capt. Al DiGiacomo of South Detective's Division said the teenager was ''beaten about the body" with a baseball bat and that Fuscellaro was struck with a broomstick when she tried to intercede on her son's behalf.
Neither victim was seriously injured.
Police said Jo Jo's is run by Fuscellaro and her son.
Other sources said the carwash and detailing shop had had a working relationship with Galati's auto body shop until recently. They said Friday's assault came after a series of phone calls in which Borgesi and Ligambi complained about the lack of referrals from Jo Jo's.
Ron Galati, 42, was recently charged with threatening to kill a federal postal inspector who is part of a task force investigating Galati for insurance fraud. At the time of his arrest, Galati was described as a friend and associate of reputed mob leader Joseph "Skinny Joey" Merlino.
