The Johannesburg Magistrates Court has ruled the arrest of the so-called Thulsie twins was lawful, based on a reasonable suspicion of offence.
Brandon Lee and Tony Lee Thulsie were detained by the Hawks on terror-related charges last month on suspicion that they were planning to bomb US and Jewish interests in the country.
The siblings challenged their arrest before pursuing a bail application, and defence lawyer Anneline van den Heever wants to take the matter to the High Court.
EWN's Gia Nicolaides explains that van den Heever is determined to have the case thrown out by appealing the ruling.
It's quite clear that van den Heever wants to make sure that the twins get off completely. If a court agrees with her that they were unlawfully arrested, those charges would be dropped against them.— Gia Nicolaides, EWN reporter
The brothers will remain in custody until Friday when a bail application is set to be heard.
