A child has died and another has been hospitalised after being trapped in a garage door in Melbourne's southwest.

Paramedics and police were called to a home in Mason Street at Newport about 7.30pm on Saturday after reports the two boys were trapped in the roller door, in the driveway of a unit block.

One was taken to the Royal Children's Hospital with serious injuries, however the other died at the scene.

According to Seven News, both boys were thought to be about 10-years-old.

Police are investigating the tragedy but say they are not treating it as suspicious.

An explanation of how the boys came to be trapped is yet to emerge.
