Police in Brighton have been accused of "kettling" a group of demonstrators during this weekend's Gay Pride event in the city.
Tens of thousands of people took to the streets on Saturday for what is thought to be the biggest festival of gay, lesbian, bisexual and transgender culture in Britain.
Entrants in the parade included businesses, charities and members of the emergency services.
Before the celebrations, Chief Superintendent Graham Bartlett, of Sussex Police, said: "Pride is a great showcase for the city and is one of the biggest events in the city's calendar, primarily celebrating our LGBT community but is open to everyone to enjoy."
Police said there were 24 arrests by 9.15pm for suspected offences of public disorder, possession of drugs, criminal damage, ABH, affray and theft.
However there was criticism of the alleged kettling of anti-cuts campaigners participating in the parade.
One member of Queers Against Cuts said being surrounded by police on horseback and on foot was "unnecessary" and "heavy-handed."
Chief Supt Bartlett said: "I'm aware that there has been a lot of social media talk around the actions of officers who were heading up the back of the parade along with the mounted Thames Valley officers.
"Police officers have always walked at the back in order to distinguish the parade from the rest of the public and to safely manage the parade through the streets to its destination in Preston Park and to make sure there is a safe distance between the horses and members of the public."
