Police have been entering in force two areas where they previously were not anxious to go. The areas are Sagrada Familia and La Carpio, both low-income parts of the city infested with crime.
Police questioned 2,355 persons between April 30 and Monday. They arrested 15, including eight who were the subject of outstanding warrants, they said Monday.
Police also confiscated marijuana, cocaine and crack. More than 300 police officers were involved in the twin operations.
