Some of Marvel Stadium’s controversial crowd controllers are among hundreds of security guards who have had their licences suspended as part of an alleged fraud that could affect top Melbourne venues and sporting events.

Victoria Police sent suspension letters last week to about 400 guards working across the security industry over allegations that “false, forged and/or fraudulently obtained documentation” was used to obtain their security licences.

Industry sources say many of the guards were on international student visas and required further references to obtain accreditation to work in the industry.

Instead of doing that, they are said to have paid hundreds of dollars to a man police are now trying to locate who allegedly helped them falsify applications.
