Halton Police have a teen in custody, following a stabbing at a home in Oakville.
Officers were originally called to the home near the QEW and the 8th Line, when a 79-year old woman was stabbed.
She's in hospital with serious injuries, and the teen originally took off.
He's now in custody, reportedly arrested while on a GO bus in Peel Region.
Police say the two knew each other, but aren't commenting on how, just yet.
They also say they aren't looking for any other suspects.
