A pervert who took photographs of teenagers in a leisure centre and two young men who used mopeds to rob elderly Asian victims are among this month's most despicable criminals.

Meanwhile a former sports coach was jailed for historic sexual offences and a teenager was imprisoned for meeting online buyers only to hold them at knifepoint.

Many of the names on August's locked up list will be spending several years behind bars, while others will be on the sex offenders register indefinitely.

We have named and shamed the most disgraceful criminals locked up in west London within the four last weeks - detailing their crimes and how long they were jailed for.

Ayman Ghazoini was under a youth referral order at the time of his robbery spree

Ayman Ghazoini responded to online ads for people selling mobile phones and mopeds, only for the sellers to be greeted with a group of men armed with knives and a bike chain.

Targeting the Brunel Estate and Great Western Road areas of Westbourne Park, Ghazolini would either threaten the unsuspecting sellers or take the mopeds for a test drive and never returned.

The 18-year-old from Second Avenue in East Acton , carried out the robberies between January 6 and January 28, 2018. The crimes led to a Metropolitan Police investigation, and Ghazoini was arrested on February 1.

Ghazoini's criminal activities were in breach of a youth referral order he had been serving, and he was sentenced to four years imprisonment for breaching that order.
