(BCTV) - They're beefing up security at the Prince George prison where the adult Chinese migrants are being held. The last of seven migrants who escaped over the weekend was recaptured Monday when he went to a house and asked for help. An intensive search turned up the other six on Sunday. Corrections B.C. says there's no problem with security, but they have added a rooftop patrol and the migrants won't be working in the kitchen. The attorney general has ordered a review into how the migrants were able to escape - that should wrap up in two to three weeks.
