CAIRO, Oct 31 (Reuters) - Dozens of Egyptian policemen suspended from work in February for growing Islamic beards protested outside the Interior Ministry on Wednesday and called on President Mohamed Mursi to secure their reinstatement.

The policemen had sought to challenge an unwritten rule that stopped members of the security forces from growing beards during the rule of President Hosni Mubarak, who used the police to crush Islamist groups he saw as enemies of the state. Mubarak was swept from power in February, 2011.

Propelled to office by the Muslim Brotherhood, a mainstream Islamist movement, Mursi had said during his campaign he had no objection to members of the security forces growing beards. Mursi himself has a beard.

"Nothing in the law prevents us growing beards," said Hany Maher, one of 64 suspended officers who were referred to a disciplinary court after growing their beards in what they described as a statement of faith, not politics.

Four of the officers challenged their dismissal in the courts and secured rulings that obliged the Interior Ministry to reinstate them. But the court orders have not been implemented.
