Meriam Yehya Ibrahim has been taken back into custody just one day after being released from prison, her lawyer, Elshareef Ali Mohammed, told NBC News. Ibrahim had been sentenced to death by hanging for converting to Christianity from Islam, but she was freed from prison when a court ordered her release.

According to Mohammed, 50 security forces arrested her at a Khartoum airport on Tuesday. He added that no reason was given for her re-arrest and that she was taken to a detention center. Her husband, Daniel Wani, and her two children went with her to the center.

"I have no more information," Mohammed said. "They knew she had been cleared by the court but they have re-arrested her -- I don't know why."

Ibrahim’s case grabbed international attention when a Sudanese court convicted her in May of renouncing her faith and of adultery. The 27-year-old, who had been jailed with her 20-month-old son, was eight months pregnant at the time with her daughter who was born in prison. The mother of two children was sentenced to 100 lashes and execution by hanging.

Following an outcry from the public regarding the case, a Sudanese appeals court overturned the lower court’s ruling. They said the judgment was faulty and ordered Ibrahim’s release.

The complaint that launched the initial case against Ibrahim was filed by her brother, who claimed her family was upset to discover she had married Wani, a Christian and a U.S. citizen. Their union led to the adultery charge since a Muslim woman’s marriage to a Christian man isn’t deemed legal in Sudan.

Ibrahim says she was Christian. But Sudanese Parliament speaker Fatih Izz Al-Deen denounced her claims, saying that she was raised in an Islamic environment and that she wasn’t wrongly convicted.

According to the Independent UK, Wani said Ibrahim was forced to give birth to her baby girl while chained in prison.
