Here are some of the people who have been sent to prison in Wales in the past week.
They include a former primary school headteacher who was caught exchanging lurid messages with an underage boy and a gang member who had been on the run for more than a year.
Here are the criminals and their crimes as they face life behind bars:
David Bundock
The former primary school head teacher awarded an MBE for services to education was caught by paedophile hunters trying to meet a 15-year-old boy.
Bundock, who was recognised for his work by the Queen in 2004, was caught in a sting after exchanging lurid messages on Grindr with an account purportedly belonging to an underage boy.

See who got locked up in February:
Miles Bishop
The crime gang member who stole luxury cars from driveways was jailed this week after he fled the UK mid-trial more than a year ago.
The 35-year-old went on the run to Dubai and Russia before he was eventually detained in Spain earlier this week.
Jamie Davies and 17-year-old co-defendant
Davies, 18, and a 17-year-old boy, who cannot be named for legal reasons, were detained after going on a crime spree armed with knives and screwdrivers.
They robbed one woman of her car and attempted to steal another two cars in the space of a few hours.

Peter Maddock
The cocaine dealer's stash of drugs had such high purity levels that it had to be "cut" before it was sold or it "would kill".
Maddock, 40, of Gwenfro, Wrexham was caught after police became suspicious when they saw his car pull up outside The Acton pub last August.

Aaron Pollard
Aaron Pollard, 23, of Gorseinon in Swansea, pleaded guilty at Swansea Crown Court to sexual activity with a child.
Pollard was jailed for 27 months and a restraining order was made against him contacting the victim for 10 years.
He must sign the sex offenders' register and a sexual offences prevention order was also made.

Luke Jones
Luke Jones tricked his way into the home of a man who had been left disabled following a stroke by pretending to be a gardener.
The 27-year-old offered to cut the vulnerable victim’s grass and then let himself into his kitchen through the back door saying he was thirsty and wanted a glass of water.
But the ruse led to him being caught after he was traced by DNA he'd left on the glass.
He was jailed for 18 months to be served consecutively to his current sentence.
