They demanded them to warm up food during their Ramadan fast.
But other lags at Gartree lifer’s jail, where the kitchen is being refurbished, are furious and claim the Muslims are getting special treatment.
Muslim inmates moaned that last year’s grub – served in flasks – was cold when they came to eat it during darkness, the end of the fasting period.
And they threatened to strike.
Now they will get meals delivered by caterers which they will warm up in microwaves.
Muslim cons at the jail in Leicestershire include killer Fadi Nasri (pictured), 33, who organised the murder of his special constable wife.
A source said: “The Muslim lads kicked up a stink last year over the food they received for Ramadan.
“And guess what? The authorities gave in and gave the green light. It’s a f**king liberty.
“If the non-Muslims asked for this they’d be told where to go.”
He warned that prisoners could smash the microwaves and use jagged pieces as weapons.
A Prison Service spokesman said: “HMP Gartree is in the process of having its kitchen rebuilt”.
“A number of microwaves have been purchased for the kitchen area and for some prisoners observing Ramadan so they can heat up food in their cells.”
