Egyptian political activist Wael Ghoneim said his security forces arrested his brother Hazem without any legal basis after he refused to ask them to keep quiet or cooperate with them.

US-based Ghoneim said in a video posted on Facebook on Thursday that security agents raided his family's home in Egypt and questioned his mother, father and brother to press him to silence him, noting that his brother had no political activity.

Wael Ghoneim, the undersecretary of the General Intelligence, accused Egyptian President Abdel Fattah al-Sisi's son of issuing an arrest warrant for his brother.

He described the Egyptian president as a dictator who arrested his brother and many of what he described as his brothers and sisters in the country.

Ghoneim said he had received an offer and a threat from the Egyptian embassy in Washington on Wednesday to silence or cooperate with the Egyptian security services, but he refused.

Ghoneim, one of the most prominent icons of the January revolution in Egypt, has published several video clips on social media recently that have aroused much controversy and criticized the Egyptian regime.

This comes in light of accelerated interactions in the wake of a call by the Egyptian contractor and actor Mohamed Ali to demonstrate on the streets of Egypt on Friday to overthrow the Sisi regime.

#savehazem My brother has been kidnapped by the Egyptian regime. He has is an apolitical person. I received a threat yesterday from the Embassy in Washington and when I rejected their offer. My brother got arrested. I am not going to back out. Please help me deal with those thugs
