Fathers' rights activists held after four-day London protest

 Two fathers' rights campaigners were arrested Friday for a four-day demonstration on top of the main entrance to London's Hyde Park, where two other protesters remain, AFP reports.

Police were alerted early Tuesday to five men and a woman who had climbed the Apsley Gate entrance to central London's biggest park.

The protesters from a group called Human Worth were acting in support of New Fathers 4 Justice (NF4J), which campaigns for greater rights for fathers when parents split up.

Of the six protesters, two men and one woman are British, two other men are French and the fifth man is an American who has lived in France for decades, according to NF4J.

Four have voluntarily come down from the arch -- one man on Tuesday, the woman on Wednesday and two men on Friday.

All four were arrested.

The two who came down Friday were held "on suspicion of criminal damage, causing a public nuisance and breach of the Royal Parks regulations", Scotland Yard police said.

"New Fathers 4 Justice want nothing less than a legal presumption of 50/50 contact for a child with their parents if they split up," the group says on its website.

The Apsley Gate is next to Apsley House, once the London home of the dukes of Wellington.

The house is open to the public as a museum, focusing on Arthur Wellesley, the first duke who served as British prime minister after defeating Napoleon at the Battle of Waterloo in 1815.
