The National Transport and Safety Authority (NTSA) director for roads safety Njeri Waithaka has resigned.

A source privy to the details told Business Daily that Ms Waithaka handed in her resignation letter a couple of days ago.

Ms Waithaka, who took over from Mr Mathew Munyao after his contract was terminated in January 2016, cited “personal reasons” for quitting the body which has recently been under scrutiny.

NTSA director-general Francis Meja confirmed Waithaka’s resignation letter but declined to give details.

“I’m aware of Ms Waithaka’s case. She has handed in her resignation letter.”

“As to when exactly she is expected to leave the agency plus other restructuring plans we may have are private information within our organisation I may not be able to disclose to you at the moment,” he said.

Ms Waithaka’s resignation has raised some eyebrows as it comes weeks after the Anti-Terror Police Unit (ATPU) raided NTSA’s offices in Upper Hill and arrested scores of the agency’s employees, including a director in charge of registration of vehicles.

ATPU officers stormed the premises in Upper Hill on January 30 in a probe into cases of double registration of vehicles.

This after it emerged that a car used to transport terrorists to the dusitD2 complex incident in Riverside on January 15 was fraudulently registered.
