A 34-year-old Thornlie man accused of shooting four cars in Perth's north-east, narrowly missing the occupants, has indicated he will plead guilty to just one of the 13 charges against him.

It is alleged Abdul Fatha Popal fired 18 rounds at cars on Beechboro Road North in Whiteman on Saturday morning.

No-one was injured.

Popal has appeared in the Midland Magistrates Court without legal representation.

He was not required to enter a plea to any charges, but indicated to the court he intended to plead guilty to just one of the charges against him.

Magistrate Stephen Sharratt said the charges against him were serious and told him to seek legal advice before his bail application hearing on Friday.

Prior to his court appearance, Popal underwent a mental health assessment and was deemed "calm and cooperative".

The court was told he did not meet the criteria for an involuntary mental health hospital admission.

The nurse who assessed him said any delusions he was experiencing were likely due to methamphetamine use rather than mental health issues.

Popal appeared to have bruising to his face and head.

He was taken into custody by heavily armed members of the police Tactical Response Group last night following an alleged police chase.

Police said Popal led them on a pursuit from Thornlie to Morley before he crashed his car and was arrested near the intersection of Camboon Road and Wellington Road.

It is also alleged police found a loaded handgun in his BMW.

Self-described 'anti-war activist'

Popal is facing charges including four counts of committing an unlawful act with intent to harm, four counts of criminal damage, and one count each of discharging a firearm to cause fear, possessing a controlled weapon, reckless driving and failing to stop.

Police today searched Popal's home in Thornlie, where he is believed to have been living with his parents.

Neighbours were shocked when told by the ABC of the charges he was facing.

They described the accused as a nice man and a "good guy", and his parents as being generous, kind and accommodating.

According to a social media profile under the accused's name, he describes himself as an "anti-war activist".
