Inmate arrested after Vic prison lockdown

An inmate who made threats causing the lockdown of a Victorian prison has been taken into custody.

Police negotiated with the 44-year-old man at Barwon Prison, near Geelong, for about two hours before he surrendered on Friday.

"The man surrendered without incident around 11.30am and was returned to custody," police said.

He reportedly had a device, believed to be ground-up match heads, strapped to himself.

Police are assessing the device.

Corrections Victoria said the incident was resolved safely and without injury.

"The situation ... has been peacefully resolved after a 44-year-old prisoner surrendered to authorities," it said in a statement.

A spokesperson would not comment on the nature of the device, saying this was part of the police investigation.
