Sudanese authorities have moved the head of the Sudanese Congress Party, Ibrahim al-Sheikh, from a hospital to an undisclosed location, a party spokesman said Tuesday.

"Security agents have moved al-Sheikh from hospital [where he was being treated] without any prior notice to party officials or his family," spokesman Bakri Youssef told Anadolu Agency.

Youssef went to on to describe the move as a "violation of law and constitutional rights."

There has been no comment from Sudanese authorities regarding the party's assertions.

Al-Sheikh was arrested in June on multiple charges, which, if proven, carry the death sentence.

His party has described the allegations as "politically-motivated," saying they came in retaliation for its refusal to accept Sudanese President Omar al-Bashir's earlier calls to engage in dialogue.
