LONDON — More than 100 people were arrested during a protest by cyclists during the Olympics opening ceremony, police said today.

Scotland Yard said two groups of protesters were arrested near the Olympic Park on suspicion of breaching protest conditions and causing a public nuisance.

The cyclists were identified as members of an activist cycling club that meets monthly for mass bike rides.

A police order had prohibited the protesters from traveling into the Olympic Park area in east London during Friday night's opening ceremony, but members had tried to pedal their way through the security cordon.
