A scuffle between cycling activists and police outside the opening ceremony resulted in 182 arrests, officials said.
Four people have been charged with various offenses during Friday night's protest, while the rest were released pending further questioning, Scotland Yard said Sunday.
Police said that they were aware that a monthly protest by cyclists was planned for Friday but ordered the protesters to remain south of the River Thames. That was to keep them from blocking more than 80,000 ticket-holding guests from attending the Olympics opening ceremony. Those arrested tried to breach the Olympic Park's security cordon, officials said.
