Some cycling activists scuffled with police officers during the Olympics opening ceremony and more than 100 people were arrested, authorities said.

The cyclists were members of a monthly cycling event called "Critical Mass" that normally passes through the area, but a police order had prohibited the group from travelling into the Olympic Park area in east London during Friday night's opening ceremony.

Dozens of cyclists were blocked by police vans from proceeding, Scotland Yard said.

Two groups of protesters were arrested on suspicion of breaching protest conditions and causing a public nuisance, Scotland Yard said.
