UAE activist Ahmed Abdul Khaleq was stripped of citizenship and deported to Thailand in mid-July 2012.
Ten people have been detained in the United Arab Emirates over allegations of threatening national security, activists say.
The UAE authorities have made the arrests over the past several days, the activists said on Sunday.
A total of about 20 people have been detained in the United Arab Emirates since July 15 on suspicion of planning “crimes against the security of the state,” the government says.
Meanwhile, activists say about 40 people, including the stateless residents of the UAE and an Omani national, have been arrested since March.
The latest arrests in the United Arab Emirates come several days after Abu Dhabi stripped activist Ahmed Abdul Khaleq of citizenship and deported him to Thailand over his online campaign for reform in the Persian Gulf littoral state.
According to the London-based Emirates Center for Human Rights, the activist was deported on July 16 on a Comoros Islands passport arranged by UAE authorities.
Abdul Khaleq and four others, including blogger and rights advocate Ahmed Mansour and economics professor Nasser bin Ghaith, were arrested in April 2011 for signing an online petition demanding constitutional reforms and free elections in the UAE. They were convicted of committing crimes against the state.
A 2009 report showed that the UAE has struck a $200-million deal with the government of Comoros to provide passports for people it makes stateless.
The Arab country prohibits any organized political opposition.
