Gano was the mastermind behind the Yar-Rimawa attack which occurred in Sokoto State on the 20th of September, 1996.
The councilor of Yar-rimawa Shehu Dan Tsamaye with the help, support and agreement of the traditional head of the area wrote a letter to the local government chairman of Goronyo, Abdullahi Abdu Dan Kura and Sarkin Gabas of Goronyo, Sambo Usman. In the letter, the councilor stated that there was a brewing conflict between the people of Yar-Rimawa and Malam Ibrahim Idris who made a sermon about the injustice being meted on Sheikh Zakzaky.
The councilor also stated in the later that Malam Ibrahim Idris and his followers were planning to seize the mosque and kill whoever dares to enter the mosque.
The letter first reached to Sarkin Gabas Usman Sambo, which after reading he took it to the Local Government Chairman who then sent it to the head Director of all local governments who then ordered that money for food and petrol should be given to the police officers he would be sending to Yar-rimawa. The commissioner of Police at that time was Gimba umar who accepted the order and sent 3 filled police cars to Yar-rimawa.
Upon the arrival of the police officers, Dan tsamaye took them directly to the mosque where he started pointing at the members of the Islamic Movement and the police officers opened fire on them. That was how Malam Ibrahim Idris and his brother Usman Iliyasu with their mother Aliyatu Rabiu attained martyrdom.
