Police in Birmingham, England, have launched a homicide investigation after one person was killed and seven others were injured in a stabbing frenzy early Sunday morning. British Foreign Secretary Dominic Raab said there was yet no indication that the incident was terror-related, but that the public should stay “very vigilant” until the perpetrators are captured. West Midlands Police were called to the scene in the center of the city shortly after 12:30 a.m. and a number of stabbings were reported shortly after. “We can now confirm that we have launched a murder investigation following last night’s events,” West Midlands Police said in a statement.
