He also was charged with three counts of obstructing a report of a crime or injury for knocking the telephone away each time Vitti tried to call 911.
The 911 dispatcher, who was finally connected with Vitti, heard a man in the background say, “I’m going to rip your head off,” police Officer Narciso Garcia said in his report.
Vitti told police when he asked McDermott to leave the home, it led to an argument and an altercation, Londonderry police Lt. Timothy Jones said.
While at the home, police seized a drug they believed to be heroin, Jones said.
McDermott’s case will now go before a grand jury for possible indictment.
