Former South African President Nelson Mandela was admitted to a hospital for tests Saturday, a government official told CBS News.

Mac Maharaj, a spokesman for the South African government, told CBS News that Mandela's admission is a scheduled visit for tests commensurate with someone of his age. Mandela is 94.

"Doctors are conducting tests and have thus far indicated that there is no reason for any alarm," read a statement issued by the country's presidency.

Mandela is in a hospital in the capital city of Pretoria, but Maharaj would not specify which one.

He was also not sure how long Mandela would stay in the hospital.

Mandela was released from a hospital Dec. 26 after receiving nearly three weeks of treatment for a lung infection and gallstones.

The first picture of Mandela after his discharge wasn't released until early February. At the time, his granddaughters said he was in good health and good spirits.

At his birthday last July, CBS News correspondent Mark Phillips was granted rare access to the party at Mandela's home.

The former president appeared to be physically healthy but detached from things going on around him, Phillips reported.
