Today at the notorious Quezon City in Metro Manila jail, they shut the doors to new inmates.
The facility was built in the 1950s to house 800 men; this week its population reached 4,024.

On certain days last week, the prison's intake reached 70 a day.
Almost 700,000 drug users have turned themselves in since the start of his offensive two months ago, living in prison, better than no life at all.

The vast majority are in for drug-related crimes including 22-year-old Rolly who was brought in last week.

Rolly will be taken to court in September but it could be months, even years before he is released.
Erwin Escalante, 37, was arrested 15 years ago and is still awaiting trial. He’s missed seeing his children grow up.
"They come seem me and I put on a smile but I come back here, to my bed and I cry, it’s hard, it’s very hard," he said.
He described how cramped conditions have become.
"It’s not humanitarian," he said. "We have 160 inmates here at Dorm 6 only, at 55 squared metres, I read a book about our rights and for inmates we should be given 4 squared metre each.
"At night we have men lying, sleeping on the floor."
