CAPE TOWN - Cape Town authorities are still searching for more suspects in connection with a series of arson attacks on Metrorail services.

In the last two weeks, there've been several incidents in which infrastructure was torched and vandalised, crippling train services.

Only one man has been charged.

It's understood investigators have questioned a former Metrorail employee in connection with recent arson attacks.

Police are trying to find the culprits who set trains alight in Kraaifontein and at the Esplanade station.

The 47-year-old man who was arrested for the Cape Town incident appeared in court earlier this week.

He'll be back in the Cape Town Magistrates Court on Monday.

Meanwhile, police and Metrorail says security along railway lines have been increased to prevent further attacks.

Metrorail has offered a R100,000 reward for information which could lead to further arrests.
