LONDON -- A Scotland Yard official says 525 people have now been arrested in London after three days of "unprecedented" rioting.
Deputy Assistant Commissioner Stephen Kavanagh says London police have been stretched to an extent never seen before and apologized that residents had to wake up to yet more scenes of destruction. He spoke Tuesday.
Commander Simon Foy said more than 100 suspects had been charged since disorder had begun.
Police in Birmingham, 120 miles (195 kilometers) north of London, said 35 people had been arrested for rioting there.
