Sudanese security forces arrested the opposition Umma party's spokeswoman Mariam al-Mahdi on Thursday, a relative said, the latest detention in a crackdown on anti-government protests.
"Security forces took her away before she could get into her car," said Habab Mubarak, a cousin.
Female relatives of dozens of people detained during demonstrations in the past month tried to deliver a statement of protest to government offices on Thursday, but many others were also arrested, she added.
Young people have staged a series of small demonstrations in north Sudan in recent weeks against rises in food prices, partly inspired by uprisings in Tunisia and neighbouring Egypt.
Police have moved in quickly to end protests, say witnesses.
