The Polish monster who tortured and killed his four-year-old stepson had been jailed in this country three times, it emerged last night.
Mariusz Krezolek had also been arrested at least six times for offences including assault and burglary. But despite his serial offending, he was never put on a plane back to Poland.
Instead, together with Magdelena Luczak, he carried out a campaign of cruelty against Daniel Pelka, starving him of food, force-feeding him salt and holding him underwater. Their brutality culminated in his death in March 2012 from a head injury, locked in a cold room on a soiled mattress.
