A Perth man accused of acting suspiciously around children at fast food outlets has been charged with a string of child sex offences.
Niaz Ahmed Ali, 58, was arrested on February 8 after police released images of a man sitting inside numerous fast food restaurants in Perth's southern suburbs appearing to conceal a recording device.
The public appeal and a mobile police facility set up at a Baldivis park on February 4 assisted police to identify the man.
"It will be alleged between 2014 and 2016 the man frequented various fast food outlets, park playground areas and shopping centres across suburbs in the South Metropolitan and South East Metropolitan policing district," a police spokeswoman said.
Mr Ali has been charged with 20 counts of indecent act with intent to insult or offend, 18 counts of a child sex offender being near a public place, eight counts of indecent dealings with a child under 13 years and two counts of indecently dealing with a child over 13 years and under 16 years.
Mr Ali, of Baldivis, appeared in Armadale Magistrates Court on Friday via video link from Hakea prison.
His lawyer indicated he would be pleading not guilty to the majority of the charges. He was remanded in custody and will face court again on May 17.
