Fake council letters announcing several bogus by-laws in the name of non-existent Islamic bodies have prompted a police hunt.

The notice, featuring a City of Greater Dandenong letterhead, has been dropped in letterboxes since late last week.

It forewarns of 10 new by-laws, including:

Alcohol and pork products must not be offered or consumed in public

Not public displays of affections

Women and girls aged above eight “shall cover their hair, arms and legs when in public”

No dog walking between 6am and 10pm

Greater Dandenong Local Area Commander Inspector Mark Langhorn told Ross and John the letter has been posted online, and the comments on social media are a concern to police.

“It’s going a little bit viral on social media and that’s our concern, some of the commentary on social media is a concern for us,” Inspector Langhorn said.

“Some people can see through it.

“I’ve got the understanding it even reached Bob Katter’s office up in Queensland.

“Some people latch onto these things and they’ve contacted the council in outrage.”

The letter says the by-laws are due to the increased number of Muslims in the area.

Police have called for public help to catch the author of the “fake and offensive” letter.

They believe the letters were placed into residents’ letterboxes and been circulating the southern suburbs since late last week.

“Every Victorian has the right to feel safe and secure in the community and in practising their faith, pursuing their values, beliefs and interests,” Inspector Langhorn said.

“We treat all crime seriously, including those that attempt to incite prejudice, racism or discrimination in our community.”
