senior officers in the Sierra Leone Army were greatly disappointed with Stevens' policies and his handling of the Sierra Leone Military, but none could confront Stevens. Brigadier General Bangura, who had reinstated Stevens as Prime Minister, was widely considered the only person who could control Stevens. The army was devoted to Bangura, and this made him potentially dangerous to Stevens. In January 1970, Bangura was arrested and charged with conspiracy and plotting to commit a coup against the Stevens government. After a trial that lasted a few months, Bangura was convicted and sentenced to death. On 29 March 1970, Brigadier Bangura was executed by hanging in Freetown. After the execution of Bangura, a group of soldiers loyal to the executed general held a mutiny in Freetown and other parts of the country in opposition to Stevens' government. Dozens of soldiers were arrested and convicted by a court martial in Freetown for their participation in the mutiny against the president. Among the soldiers arrested was a little-known army corporal, Foday Sankoh, a strong Bangura supporter, who would later form the Revolutionary United Front (RUF). Corporal Sankoh was convicted and jailed for seven years at the Pademba Road Prison in Freetown. In April 1971, a new republican constitution was adopted under which Stevens became president. In the 1972 by-elections, the opposition SLPP complained of intimidation and procedural obstruction by the APC and militia. These problems became so severe that the SLPP boycotted the 1973 general election; as a result the APC won 84 of the 85 elected seats. An alleged plot to overthrow president Stevens failed in 1974 and its leaders were executed. In mid-1974, Guinean soldiers, as requested by Stevens, were stationed in the country to help maintain his hold on power, as Stevens was a close ally of then-Guinean president Ahmed Sékou Touré. In March 1976, Stevens was elected without opposition for a second five-year term as president. On 19 July 1975, 14 senior army and government officials, including David Lansana, former cabinet minister Mohamed Sorie Forna (father of writer Aminatta Forna), Brigadier General Ibrahim Bash Taqi and Lieutenant Habib Lansana Kamara were executed after being convicted of attempting a coup to topple president Stevens' government. In 1977, a nationwide student demonstration against the government disrupted Sierra Leone politics. The demonstration was quickly put down by the army and Stevens' own personal Special Security Division (SSD), a heavily armed paramilitary
