Meanwhile, the familiy homes of some activists, including Adly, and journalist Mahmoud al-Saqqa, were raided by police.
According to the statement, the Interior Ministry said it will deal strictly with any actions that violate public security, such as attacks against key public institutions or police facilities.
In a speech on Sunday, President Abdel Fattah al-Sisi said attempts to undermine security and stability would not be tolerated and that the police and military should be ready to react to any trouble.
"The Shorouk newspaper published a report on April 21 about a presidential meeting in which Sisi said he will not tolerate protests like the the so-called 'Friday of Land'. However, the presidency denied the news story the same day. A few hours later, the random arrests took place in downtown Cairo and Alexandria," the statement said.
The statement also called for canceling the Protest Law, which the NGOs described as "oppressive".
It also urged the Interior Ministry to stop violating the rights of people to gather peacefully, while calling on authorities to stop fabricating charges against activists.
