Paramedics frantically trying to save life of man, 40, who was fatally tasered by police after 'biting an officer and trying to steal his gun'

Paramedics battled to save the life of a 40-year-old man, who died after being tasered by police following a confrontation.
Shocking footage captured by a passerby shows paramedics working to help the indigenous man, being held down in the East Perth Officeworks car park.
Police say they were driving past the Officeworks on Lord Street when they were waved down by a member of the public who was with the man, who required urgent medical assistance.
But when they tried to help him, he allegedly became aggressive and a struggle ensued, resulting in police having to call for back-up and two officers being injured.
The unidentified man allegedly tried to grab a gun from an officer and repeatedly tried to bite another officer's arm, Perth Now reports.
Another officer received cuts, scratches and bruises trying to restrain him.
The taser was used to restrain the man and police say he became unresponsive, with witnesses claiming the man took some time to become affected.
During the struggle, customers were kept inside the office supply store for safety.
When they emerged - they came across paramedics attempting to save the man's life.
He was rushed to Royal Perth Hospital but was unable to be saved.
The Major Crime Squad and Internal Affairs Unit is investigating and wants to speak to a man who visited Perth Police Station on Friday and said he had information that could assist the investigation.
