Citadel Security Services (C-Sec) handles law enforcement on the Citadel. It is a volunteer police service answering to the Citadel Council, and is headed by an Executor who often liases between C-Sec and the Council. The current Executor is a turian, Venari Pallin, whose office is located within the Embassies of the Presidium, near the Citadel Tower. The majority of officers are turian, though many are also salarian, asari and human. The 200,000 constables of C-Sec are responsible for maintaining public order in the densely populated Citadel, as well as providing pirate suppression, customs enforcement, and search-and-rescue throughout the Citadel and surrounding space.
