Two prisoners have escaped from HMP Pentonville (UK), the Ministry of Justice (MoJ) has said.
The escape was discovered when officers carrying out checks found two pillows made to look like bodies in the prisoners' beds on Monday.
It is understood the inmates, aged 28 and 31, used diamond-tipped cutting equipment to break through cell bars before they scaled the perimeter wall.
Both were on remand, one for attempted murder and the other for burglary.
Inmates removed after HMP Bedford riot.
The men were not required for prison work, which is why they were not reported missing until 12:00 GMT, the BBC's home affairs correspondent Danny Shaw said.
He added staff were expected to conduct a visual check on prisoners at about 07:00 GMT.
It is understood pillows in their cells were made to look like bodies, but it's not clear if they had other objects or coverings on them.
Initial reports suggested mannequins had been left in the beds.
A prison spokesperson said: "Public protection is our top priority and we take escapes from custody extremely seriously.
"We are working closely with the police and are urgently investigating the matter."
The escaped prisoners were on G wing, the same wing where 21-year-old prisoner Jamal Mahmoud was fatally stabbed last month.
Basana Kimbembi, 34, has been charged with his murder.
Following the attack, about half of the 200 prison officers passed a vote of no confidence in Pentonville governor Kevin Reilly.
