Mexico City prosecutors says police have freed 12 people who were forced to work in a factory inside a rehabilitation center that could be linked to a drug clinic where 105 "slave workers" were rescued last week.

City prosecutors say one man was arrested during the raid Friday in the northern borough of Atzcapozalco. They say police were alerted by a man who reported being kidnapped and forced to work at the drug clinic putting together boxes for packaging tequila bottles.

Last week, police rescued 105 people from a rehab center in the eastern Iztapalapa borough where they were forced to make clothing clasps and shopping bags. Police arrested 25 people.

Prosecutors say they are investigating links in the two cases.
