Philippine police reported the 22 inmates, many of them convicted of illegal drug-related offences, have escaped from a city jail south of Manila, with three being recaptured immediately.
Police say a jail guard was escorting a prisoner back to a cell Friday in Bacoor city in Cavite province when inmates rushed out and overpowered the guard.
Police say 22 inmates dashed to freedom in the densely populated district. Three were recaptured and the rest were being hunted by policemen.
Philippine jails often jammed beyond capacity, are notorious for jailbreaks due to poorly maintained conditions, a lack of guards, corruption and a shortage of maximum-security facilities for high-risk detainees like insurgents.
