 The UDT coup was a "neat operation", in which a show of force on the streets was followed by the takeover of vital infrastructure, such as radio stations, international communications systems, the airport and police stations.During the resulting civil war, leaders on each side "lost control over the behavior of their supporters", and while leaders of both UDT and Fretilin behaved with restraint, the uncontrollable supporters orchestrated various bloody purges and murders.UDT leaders arrested more than 80 Fretilin members, including future leader Xanana Gusmão.
