CAIRO, March 17 (Reuters) - Egyptian villagers on Sunday beat to death two men accused of violent crime and hung their bodies from a lamppost, in one of the country's most gruesome examples of vigilante justice.

A mob chased the men through the village of Mahalt Ziyad in the Nile Delta, around 140 kilometres (87 miles) north of Cairo, said Mudeer Amn al-Gharbiya, a local security official. They strung up the corpses in a public place as a warning to others.

The villagers had accused the men of attacking women and children, kidnapping and theft, the official said.

Security has deteriorated since the overthrow of President Hosni Mubarak in a popular uprising two years ago and Egyptians complain of growing crime and an ineffective police force.

Local people meted out similar punishments in two other Nile Delta towns in recent weeks, killing three. Last month one person was killed in another case of vigilantism in a governorate south of Cairo.

Small numbers of groups called "popular committees" emerged during the 18-day uprising that toppled Mubarak when the police disappeared from the streets. They carried out tasks such as street patrols and protecting property but usually without resorting to such mob violence. (Writing by Sylvia Westall; Editing by Stephen Powell)
