A primary school worker in his 30s and a student are amongst those who have already pleaded guilty to looting and rioting in courts on Wednesday.
31-year-old Alexis Bailey from Battersea in South London pleaded guilty to burglary after being arrested in Croydon.
He will be sentenced at a later date and was granted bail, but with a curfew.
Defendants scheduled to appear today are from a number of backgrounds and up to 40 years old.
David Cameron said earlier 160 people had been charged with rioting related offences and courts were working through the night to process them.
The prime minister said: “As I speak, sentences are already being passed, courts sat through the night last night, and will do again tonight. It is for the courts to sentence, but I would expect anyone convicted of violent disorder to be sent to prison.”
Despite the promise, some pleading guilty to rioting are already being let off with fines. David Attoh was told by chief of magistrates Melvyn Marks not to get into trouble again and fined £150: “You have a bright future ahead of you, if you get into trouble again you are going to jeopardise that future.”
The 18 year old student pleaded guilty to stealing two Burberry shirts in Hackney on Sunday evening.
