Man charged over Aly office knife incident

A man who allegedly brandished a large kitchen knife at the electorate office of federal Labor MP Anne Aly has been charged and will face court next month.

The incident unfolded at the member for Cowan's office in Perth's north, which is within a shopping centre, on August 5.

Dr Aly, the first Muslim woman elected to federal parliament, said her staff were separated from the man by security glass and kept him calm until police arrived.

"This is obviously an issue with mental health," she told 6PR radio the following day.

"He came in wanting to speak to somebody. It was very difficult to make out exactly what his issue was."

The 55-year-old man was taken to Joondalup Health Campus and on Friday, police said he had been charged with being armed in a way that may cause fear.

He is due to face Joondalup Magistrates Court on September 2.
