Arriva apologised today after two minor collisions in Mrabat Street, Sliema at about 1 p.m.  caused congestion until the vehicles were cleared by wardens and could continue with their journey. 

"Arriva would like to extend its apologies to the travelling public for any delays in the services on routes 22, 32 as well to residents in the area who might have been affected," the bus service operator said.
