LONDON (Reuters) - Royal Navy bomb disposal experts were travelling to a house in Plymouth on Tuesday to deal with firework-like devices discovered following the arrest of suspected anti-G20 summit protesters.
Police arrested five people over the weekend who they believed were planning to take part in demonstrations when world leaders arrive for the G20 summit on the financial crisis to be held in London this week.
Detectives said a search of one suspect’s house in Plymouth had uncovered several imitation firearms, improvised explosives made of fireworks and material “relating to political ideology.”
“As a precautionary measure, Royal Navy bomb disposal experts will be visiting the premises shortly to ensure the devices are made safe,” police said in a statement.
Three men aged 16, 19 and 25 and a 20-year-old woman are still being quizzed under counter-terrorism powers. Another woman, 20, was released after questioning.
Thousands of officers are taking part in a huge security operation this week in London with anarchists threatening to bring chaos to the streets of the capital before and during the G20 meeting on Thursday.
Police said the Plymouth investigation had no links to any religious groups.
