Justice Minister Frank Musa Dean stated that those being denied admission at the facility were inmates accused of minor offences.
“Where no damage was done or nobody was wounded, people arrested on minor charges are to instead be returned to communities and kept under the watch of community leaders,” Mr Dean said.
It follows local media reports that prison guards were refusing to admit new inmates as part of an ongoing strike over a delay of salaries. Prison officials have denied the claim.
The Liberian prison was built to hold around 300 inmates when the population of Monrovia was about 300,000. It now holds over 1,600 inmates in a city of about 1.5 million people.
Inmates at the facility include convicted murderers and armed robbers.
“Of course when there is an increase in population, correspondingly there’s an increase in crime rate,” Mr Dean said. “And there’s a challenge.”
Engineers from the ministry of public works are working on a blueprint to construct additional wings of the prison that will take up to 1,000 inmates, according to the justice minister.
