As the sun set on Monday evening, carnival-goers kept on dancing.

Revellers watched the colourful parade from balconies on Ladbroke Grove while people of all ages took to the streets to celebrate.

Colette Ford from Salisbury was among those taking part in the carnival. Dressed in an elaborate Dominator costume which cost £170 to match the 50 Shades Of Paradise float, she said: "It's a lovely amazing atmosphere to be part of a truck."

Meanwhile keen dancer Jasmin Castrioty, 25, said she had "loved" her first experience of carnival, saying: "The rhythm is absolutely stunning. I can actually feel it. Next year we are coming back."

Teacher Jan Harvey, who is originally from Jamaica, said: "Everybody is enjoying themselves, there is no trouble and there is a good atmosphere."

Conall De Hoog, 18, was impressed by what he described as calm scenes during his first carnival.

"It all seems calm at the moment - maybe later but at the moment it's fine," he said.

Scotland Yard said that as of 7pm on Monday there were 160 arrests during the day.
