The case against the 42-year-old warrant officer, Constable Olebogeng Martin Molatlhwe, 30, and police reservist Constable Edward Arendse, 36, was postponed to February 3 for a formal bail application, Colonel Priscilla Naidu said.

"We cannot release the name of the warrant officer because he has not appeared in the identification parade and this may jeopardise our investigation," she said.

Naidu said on Saturday around 2pm, three police officers in uniform went to a foreign-owned tuck shop in Magoda Street, Galeshewe, and allegedly robbed it.

"The complainant alleged that the police officers informed him that they were searching for illegal cigarettes. Two officers entered the shop while the other person remained outside," Naidu said.

"The place was searched and cash to the amount of R9000 was taken. Witnesses alleged that the police officers drove off in a marked police vehicle from SAPS Roodepan."

She said a case of robbery was opened at the Galeshewe police station. The officers were arrested on Monday afternoon.
