Metrorail Gauteng has condemned an attack on four staff members at Pretoria Station on Wednesday evening.

A train driver, train guard, security guard and a customer service official were attacked by a group of angry train commuters who also stoned the windscreens of trains servicing the Mamelodi Corridor route launched early last year.

Metrorail said increasing attacks on its staff and trains undermined efforts to improve its commuter rail service in Gauteng province.

“This is totally unacceptable, and I want to assure both staff and commuters that the company has already started to work with law enforcement agencies to ensure that those responsible are brought to book,” Metrorail Gauteng acting provincial manager Goodman Matampi said.

“Metrorail will not leave any stone unturned until the perpetrators are behind bars”.

Matampi said that Metrorail would reward people that came forward with information to help with the arrest and successful prosecution of the perpetrators.
