This according to family lawyer Philip Smit.

The Moti brothers Zia (15), Alaan (13), Zayyad (11) and Zidan (6) were kidnapped in Polokwane on Wednesday en route to school.

It's understood the car they were being driven was cut off by two others along the Tzaneen bypass before seven men made off with the boys.

Their driver was left at the scene.

Smit says the family has reason to believe kidnappers will make contact.

"There were no calls yet made by the criminals, so we do not know what the plan is, but we suspect it is a type of a ransom situation. That's all we can think of at this stage."

It's unclear why the family believes the kidnappers are in it for the cash.

"That's a personal opinion. I'm not willing to divulge any information with regards to that but we've got good reason to believe it might be," Smit adds.

He adds the family is in a state of panic as the search for the siblings continues.

"The family is very much worried and stressed out, although they have high hopes that the family will be found safely.

"They are requesting prayers, as well as any assistance of people, see the faces that match the pictures."
