A Christchurch bus driver who made a toilet stop says he was robbed at knifepoint.
The bus driver told police he had stopped outside a toilet block at Broadhaven Park in Parklands on Saturday at around 7.15pm.
He says two men armed with a knife approached him and demanded money.
"They fled the scene in a white vehicle travelling east along Ascot Drive with a number of coins from the driver's cash box and the driver's wallet and personal cell phone," said Constable Justin Robbins.
The two men are described as European in their late teens/early 20s and of slim build.
One with short brown hair was wearing a blue-checkered shirt and blue jeans, the other with short black hair wearing a black Adidas top and black tracksuit pants.
