FBI officers in the US are today searching two locations in the Boston area in connection with the attempted bombing in New York’s Times Square this month.
"Two search warrants are being executed in the Boston area in relation to the Times Square bomb. They are looking for evidence related to the investigation," FBI spokesman Richard Kolko said.
Tensions are high in the US following the failed car bomb in Times Square on May 1st.
Prosecutors have charged Faisal Shahzad (30) a naturalised US citizen born in Pakistan, in connection with the attack.
Mr Shahzad is accused of driving a crude homemade bomb of gasoline, propane gas, fireworks and fertiliser into Times Square.
US attorney general Eric Holder said last weekend evidence shows a Pakistan Taliban group closely allied with al-Qaeda was behind the attempted bombing.
