Police are dealing with another “suspicious substance” incident in Parliament less than 24 hours after Labour MP Mohammad Yasin’s office was targeted with a package containing a non-harmful liquid. Guido understands Rupa Huq’s office has been evacuated as have other offices on the first floor of Norman Shaw North building. The incident involves two packages. Specialist police and ambulance crews are in attendance. Police said they were investigating whether yesterday’s incident – which saw two people taken to hospital as a precaution – was linked to threats against Muslims. Now Parliament says police are probing whether the two incidents are linked:

“The Met Police are currently investigating suspicious items of mail in Norman Shaw North. We cannot provide any more details at this stage. This is further to the two items investigated yesterday, both of which were found to be non-harmful. The Police are investigating the content of the letters to identify any potential links.”

Yikes…

UPDATE: MPs, researchers and Parliamentary staff have received an email warning them that there have been four unknown substance incidents in two days. It reads:

“The Met Police are currently investigating two suspicious items of mail in offices in Norman Shaw North…

“Yesterday a suspicious substance in an office in Norman Shaw North was investigated by the Met Police and was found not to be hazardous. The affected area was temporarily cordoned off but no evacuation was necessary… A further letter was investigated in an office in Portcullis House yesterday evening and found not to be harmful. This makes a total of four incidents in two days at time of writing.”
