A police officer was lucky to escape injury when a man stabbed at the window of a police car in Eltham overnight.
The incident unfolded when officers were called to reports of an armed man who appeared agitated, at the intersection of Reynolds and Main roads, on Tuesday 6 October about 10pm.
Responding police received a number of calls from the public about the shirtless man who was pacing the street and holding two knives.
When police arrived, the man charged at police and broke the knife as he stabbed at the officer's closed window.
In difficult and dynamic circumstances police were able to establish a roving cordon, while the Eltham man ran and yelled at police, before they negotiated with him to drop the knives.
The 21-year-old man was taken into custody and transported to hospital with a self-inflicted injury and for assessment.
North West Metro Inspector Zorka Dunstan said the incident overnight highlights the very difficult and challenging scenarios police can face day in and day out.
"The responding officers are to be commended for their actions in a very dynamic incident," Inspector Zorka said.
Anyone who witnessed the incident is urged to call Crime Stoppers on 1800 333 000.
