Attacks on CTU Los Angeles

Although it may seem like a secure envirnoment, CTU Los Angeles has often been the site of attacks designed to hinder or halt the investigation of the agency.

There have been three attacks on the building, all of which have crippled it and left many CTU agents injured and dead.

Day 2 Bombing of CTU
During Day 2, three bombs were placed in CTU Los Angeles and detonated. The attack destroyed a significant part of the building and killed many key CTU Agents.

The attack was planned by Wald and his men who wanted to stop the investigation into the planned nuclear attack on the city that day.

Wald and his crew, including undercover CTU Agent Jack Bauer, cut off main phone lines to CTU Los Angeles, forcing them to call out the phone company to repair the problem. When the phone company arrived, Wald took one of the men hostage and stole the uniforms for his crew. With the uniforms and ID, they were able to enter the building and place the bombs before escaping.

Jack Bauer was able to free the captured phone company employee without losing his cover, who went and warned Tony Almeida. Almeida ordered an evacuation of the building but the bombs went off during it.

Amongst the agents killed in the blasts was Paula Schaeffer. Although the blasts destroyed much of the building, CTU were still able to operate from it for the remainder of the day.
