Four people have been arrested after Pro-Palestinian activists smashed windows and daubed paint over a business they believe helps supply weapons to the Israeli army. The men are being held on suspicion of causing criminal damage after the office building in Birmingham was vandalised at 7am today (Mon). Several windows were smashed and the doors covered in 'blood red paint' at Number 55 Colmore Row by protesters from Palestine Action. The group said they were targeting property company LondonMetric, alleging it was in partnership with Israel's largest weapons company Elbit Systems. Palestine Action posted on X, formerly Twitter: "Palestine Action spray, smash and shut down the landlords of Leicester’s Israeli weapons factory! "London Metric have Palestinian blood on their hands." West Midlands Police have placed a cordon around the scene near to Birmingham Cathedral and the city's Frankfurt Christmas Market. A force spokesperson said :"We've arrested four people on suspicion of criminal damage in Birmingham city centre this morning (27 November). "We were called to an office building on Colmore Row, Birmingham at around 7am to reports that a group of people were at the location and had thrown paint at the building. "A number of windows have been broken and what we believe to be paint has been daubed on the building. "Four men have been arrested on suspicion of causing criminal damage and are currently in custody." LondonMetric have been approached for comment.
