CIUDAD JUAREZ, Mexico: President Felipe Calderon has promised federal investigations into all complaints of extortion and kidnapping in a Mexican border city overwhelmed by drug gang violence. Calderon made the pledge after meeting Wednesday with hundreds of residents of Ciudad Juarez, across the border from El Paso, Texas.

It was the second time Calderon visited the city since the Jan. 30 massacre of 15 people in a working class neighborhood fueled anger over the government's failure to stem the bloodshed. The government has vowed to implement a new plan that will focuses on improving law enforcement and addressing the social ills feeding organized crime.

Calderon said he has instructed his security Cabinet to immediately look into complaints of extortion and kidnapping in Ciudad Juarez.
