One man is in hospital after he and his brother leapt onto another car in a bizarre case of road rage.

It happened on Yonge Street at Briar Hill Avenue, just north of Eglinton Avenue, around 11:20 a.m. on Monday.

The two brothers were driving when they were rear-ended, Toronto police told CityNews. Both brothers jumped out of their car to talk to the other driver. He took off, but the brothers jumped on the hood to try to stop him.

One of them was thrown from the vehicle. He was taken to hospital, where he remains in serious but stable condition.

The other brother was taken into custody.

Police are asking for witnesses to come forward.
