The jailing of hundreds of people involved in last week's riots has led to the prison population in England and Wales to reach a record high
There has been a spike in arrests and convictions recently after the wave of violence and unrest in cities across the country.
Around 1,500 places remain before the usable operational capacity of 88,093 is reached.
The rise of more than 100 per day since last week comes after some 1,300 people have appeared in court charged with offences linked to the riots and looting.
2 people were jailed for four years each after setting up Facebook pages which encouraged people to riot.
