Grandmother forgives man who allegedly carjacked and attacked her in Melbourne

A Melbourne grandmother has forgiven the man who allegedly carjacked and abducted her at knifepoint.

A 30-year-old man was arrested just after midnight following a large-scale police chase that involved dogs and a helicopter.

The man allegedly climbed into the passenger seat of 74-year-old Mary Tetradi's car after she had finished doing her shopping at a centre on Beach Street in Frankston about 4.30pm yesterday.

He allegedly threatened her with a knife and demanded she drive to the hospital, before dropping her off at a service station in Frankston North about half an hour later.

She was uninjured.

"He was very annoyed I was not upset. He said 'aren't you scared?'. You asked me to take you to hospital and I will take you to hospital," Tetradi said.

Her car was found crashed into a pole on Frankston-Dandenong Road about 6.25pm. Police were told the driver had run from the scene.

The same man allegedly then used a knife to threaten a man and steal his white Toyota Camry sedan on Belvedere Road in Seaford about 7.30pm.

The pursuit started about 11pm when police allege the car failed to stop for them.

The car was tracked by helicopter and police laid spikes on Parer Street, bringing the chase to an end just after midnight.

The man, from Carrum Downs, allegedly ran from the car and was caught by the dog squad.

He was taken to hospital, where he remains under guard.
