    Rifle ammunition was found Friday at a home connected to the man suspected of threatening Fairfax High School on social media, according to authorities.

    City of Fairfax Police, in conjunction with the Fairfax County Police Department, are searching for 18-year-old Ishmael O’Brien Lionel Harrison who they said made threats on social media toward Fairfax High School Feb. 21. Harrison should be considered armed and dangerous, police say.

    On Friday, police say they executed a search warrant at a home connected to Harrison and found the rifle ammunition. Police say Harrison is suspected of threatening harm to police and others and is evading arrest.

    City of Fairfax Police said both they and the Fairfax County Police Department immediately attempted to serve two warrants – including one for threats to commit serious bodily harm to persons on school property – to Harrison after they were obtained but have not been able to locate him.

    Another warrant was also obtained for possession of child pornography.

    Police said they were actively investigating a threat against Fairfax High School Feb. 22, one day after they said Harrison made the threats. His name was not released at the time. Police say they initially interviewed Harrison who cooperated with police but there was not evidence of firearms at the time. They say they later got new information which led to them searching the home and getting warrants for his arrest.

    Officers say security has been enhanced at Fairfax High School and other city schools. Police say they are working with federal, state and local law enforcement as they search for Harrison.

    According to police, Harrison is a 5-foot-7, 170-pound black male with black hair. He is known to drive a black two-door 2002 Acura with Virginia registration VYZ-8467.

    Anyone who knows of Harrison’s whereabouts should call either City of Fairfax Police at 703-385-7924 and Fairfax County Police Department at 703-691-2131.
