Dozens of people marched through Norwich as part of a global campaign against human trafficking.

The Walk for Freedom was held in the city on Saturday morning, with 140 people donning black and putting tape over their mouths to represent those who cannot speak for themselves.

The local event was organised by the Proclaimers church, which has bases in Norwich and Ipswich, while the global initiative is the brainchild of campaign group A21.

Gemma Neill, coordinator of the walk, said: 'We were thrilled to have so many people take part. It's important that as members of the public we draw attention to this issue and make people aware of the magnitude of it.

'But we were even more thrilled by the response of passers by.'

Last year, 200 walks took place in 28 countries.
