Police also clashed with protestors on Wednesday evening

Four men and two women, all from Sheffield, were arrested in the city centre on Thursday night and were due before magistrates on Friday.

A 16-year-old girl from Southport, Merseyside, was given a verbal caution.

The protesters had been involved in what police described as "minor disorder" in Westfield Terrace.

Police praise

They were arrested for public disorder offences, being drunk and disorderly and obstructing police officers.

About 100 people from various groups had gathered earlier on Thursday at Cathedral Square - the agreed site for a demonstration outside the venue where ministers were meeting.

One protestor said officers had praised those who gathered for their peaceful approach to the demonstration.

But about 50 people, including children, were later penned into nearby Westfield Terrace for about two hours.

Protesters 'trapped'

Protesters who say they found themselves trapped by riot police criticised the approach.

Earlier on Thursday three people appeared before Sheffield magistrates charged with public order offences following scuffles with police on Wednesday.

Justice ministers from the world's most powerful countries will discuss Africa and counter terrorism during their last day of talks in the city on Friday.
