West London Police Clampdown

To update on todays earlier events, it now seems clear that no bombs went off in West London, but the loud bangs that people heard were probably tear gas/stun guns/other 'specialist' tactics alluded to in the Police statement given this evening.

All four suspects are now in custody, including, it appears, one man arrested in Rome.

It's still not clear whether the dramatic arrest of two women at Liverpool St Station is connected. Police were described as 'sitting on top' of both the women for some minutes until reinforcements arrived.

And so the tension increases. In small ways, little by little.
