Package with explosive device sent to London reported to have 'Bus Eireann, Dublin' as sender's address

Gardaí are conducting a high-level security investigation after reports that at least one of the three explosive packages in London were sent from Ireland.

Update: The jiffy bag reportedly sent to Waterloo appears to have its sender's address as Bus Eireann, Dublin, but the company said gardaí had not been in touch.

"Bus Eireann are currently not aware of this and we have no further comment," a spokeswoman said.
