Luigi Mangione’s Life Inside MDC Brooklyn Jail Revealed

Luigi Mangione is locked up in a notorious NYC federal detention center known for its horrible conditions — and TMZ has been given the lowdown on his life behind bars.

Sources with direct knowledge tell us … Mangione is tucked away in “administrative segregation” at MDC Brooklyn — with a group of inmates separated from the general population because they require heightened security.

In the case of Mangione, he became infamous after being arrested for the high-profile murder of UnitedHealthcare CEO Brian Thompson — so he could be a target for other inmates. Hence, the extra security.

Our sources say Mangione’s locked up in a single cell — nobody’s rooming with him. But, the cells are close together and inmates frequently talk to one another.

We’re told there aren’t TVs in the segregation unit … so, there isn’t a lot to do during the day.

Luigi does get a chance to stretch his legs … enjoying one hour a day out of his cell in the rec pen — a large cage where he will be uncuffed. Our sources say sometimes there’s a basketball or a stationary bike in it, depending on which cage is used.

For his entertainment, we’re told Luigi can buy an MP3 player and songs through the commissary — if someone puts money in his account, that is.

Inmates are limited to $350 of spending a month — though for the holidays they’re given an extra $100 added to their limit.

As you know … Luigi is charged with fatally shooting Thompson in Midtown Manhattan earlier this month — with authorities throwing Mangione in MDC Brooklyn after he was extradited back to NYC from Pennsylvania.

Luigi’s facing murder charges at both the state and federal level … and, he’s allowed to meet with his attorneys while locked up in MDC Brooklyn.
