A pair of siblings were stabbed and critically wounded inside a home in west Columbus, just south of Hilliard, Tuesday morning.

The brother and sister were inside a residence in the 5200 block of Frisco Drive when an unknown attacker entered the home and stabbed both of them before fleeing at 10:20 a.m., according to Columbus police.

Both were taken to OhioHealth Grant Medical Center in critical condition. Investigators reviewed 911 calls and it appears the pair did not know the attacker, said Sgt. Dean Worthington, a spokesman for Columbus Division of Police.

Police were still searching for a suspect as of 1 p.m.

Anyone with information is asked to call Columbus police investigators at 614-645-4730 or remain anonymous by calling Central Ohio Crime Stoppers at 614-461-TIPS(8477).
