Kuwaiti authorities arrested a political activist and prominent poet over tweets criticising the government, his family said.
Jamal Al Sayer, also a businessman, has been charged with "insulting the Amir, spreading fake news that could harm the state's image and misusing his mobile phone", Muhannad Al Sayer, his nephew and his lawyer, told Reuters.
Al Sayer was arrested on Monday evening after three police cars intercepted him in the street, he added.
The government and its interior ministry did not respond to requests for comment.
"Your highness (the amir) and your highness the crown prince, the situation has become unbearable. You have allowed the government to disrupt and violate the constitution, defying the parliament and the people's will," Sayer said in a tweet on June 28.
His arrest sparked outrage among some MPs.
