Egyptian police have arrested a spokesman for the Muslim Brotherhood (MB) as part of the army-backed government’s unrelenting crackdown on the movement.

Gehad el-Haddad was detained in Cairo on Tuesday to become the latest MB member to be jailed since the July 3 coup, which removed President Mohamed Morsi from power.

An arrest warrant had been issued earlier for Haddad, who was active on social networks, but he had managed to escape arrest for weeks.

He was finally arrested in an apartment in the capital’s Nasr City neighborhood along with other pro-Morsi figures including the former governor of Qalyubia Province, Hossam Abu Bakr.

More than 2,000 members of the Brotherhood have been arrested since Morsi's ouster, among them the movement’s supreme leader, Mohamed Badie.

On Tuesday, Egyptian authorities ordered freezing of the assets belonging to Badie and two of his deputies as well as three other senior MB leaders.

On August 14, hundreds of people were killed when the military-backed interim government attacked two pro-Morsi protest camps in Cairo, including in Nasr City.

The bloodshed sparked international condemnation and prompted world bodies to call for an independent investigation into the violence.

About 1,000 people died in a week of violence between Morsi supporters and security forces following the mid-August massacre.

Despite the bloody crackdown of pro-Morsi protests, his supporters continue to hold protest to demand the reinstatement of the country’s first democratically elected president.
