Three people have been arrested following a number of incidents in Sunbury overnight.
A 29-year-old St Albans man was arrested about 2.30am after falling through the ceiling of a property at Fullwood Drive.
Police allege the man was also involved in an aggravated burglary and false imprisonment at another Fullwood Drive property earlier in the night.
The man was taken to hospital under police guard.
No one else was injured and no items were stolen during the incidents.
Two others, who were allegedly travelling with the St Albans man, were arrested earlier in the night and are assisting police with their inquiries.
Police said they observed a vehicle with false number plates on Pugh Court about 1.30am. When they attempted to intercept the vehicle, it fled the scene.
A 29-year-old woman was arrested soon after, following a brief foot chase.
A 38-year-old man was arrested in the same vicinity with the assistance of the dog squad.
