Mr Afa Alhassan Kasim, a driver of a 26 seater vehicle, said when the six armed robbers stopped them they spoke in Dagbani and Fulani languages by ordering all the passengers to get down and collected all their phones and money.
He said they took his phone and GH¢220.00 after breaking the side glasses of his vehicle and took GH¢3,000.00 from one of the passengers who was travelling to Tatale and this is besides the money and other valuables collected from other passengers.
Fuseini Bigger, another driver of vehicle, said they also broke the windshields of his vehicle and took all their phones and money of passengers.
Mr Abdul-Majeed Chendo, Secretary of Yendi Ghana Private Road Transport Union (GPRTU) of TUC, appealed to the Regional Police Commander and Yendi Divisional Police Command to extend the Police Patrol Team to the Yendi Tamale road to curb the frequent robberies on that stretch.
He said this year alone, there has been more than six robbery cases on the road which is not a healthy situation.
