A 19-year-old man allegedly stabbed his grandparents during an argument in their Bat Yam assisted-living apartment on Monday morning.

The grandfather, 80, was taken to Wolfson Medical Center, Holon in serious condition. The grandmother, 70, was also taken to the hospital with light injuries.

An initial police investigation reveals that the grandson and grandfather were in the middle of an argument when the grandson found a knife and stabbed his grandfather repeatedly. When his grandmother was awoken from the argument, he stabbed her as well.

The perpetrator was apparently recently divorced and had been living with his grandparents in their assisted-living apartment.

Police are currently searching after the suspect, who has a violent criminal history.
