Shocking: Checkout some in-human pictures of inside world's most crowded prison where 30 convicts share each cell

Inmates lying on the floor

Quezon City prison in Manila is notorious for its horrid living conditions, where men are even forced to take turns sleeping on the cement floor.

These are the jaw-dropping images that expose the brutal life endured by prisoners in Manila.

Quezon City prison was built for 800... but it now houses 3,800 inmates.

Located in the capital city of the Philippines, the living conditions are so harsh that some prisoners do not even have enough space to sleep on the floor.

Instead, prisoners are forced to take turns to lie down.

One prisoner Raymund Narag was 20 when he was sent to the jail after being convicted of murdering a young man.

He served seven years in the prison, and have since spoken out about the conditions there.

Mr Narag claims he shared one cell with 30 others, living on a diet of dried fish.

Speaking of life behind bars, he has previously said: "I saw firsthand the intricacies of managing a crowded, underfunded, undermanned prison institution."

The Philippines is moving towards a federal form of government by 2022, after President Rodrigo Duterte agreed with the leaders of Congress to set up a body to amend the constitution.

Duterte, who swept to power in May on a wave of public anti-establishment frustration over crime and poverty, wants to devolve power to long-neglected poor provinces and spread wealth more evenly.

House Speaker Pantaleon Alvarez said: "By granting more, and specific, powers to the state governments, the red tape that leads all the way to Manila will be shaved off, reducing delays and uncertainties inimical to business."
