Scottish police announced on Saturday that they are investigating a series of violent incidents that took place in Edinburgh on Friday evening, leaving five men injured, with the attacks suspected to be anti-Muslim in nature.

Police said they arrested a 36-year-old white Scottish man and confirmed that there is no further threat to the public at this time.

Videos shared online appeared to show a shirtless man, believed to be the suspect, walking through the Scottish capital carrying a large knife.

In a statement, police said that Scotland’s Counter Terrorism Unit is leading the investigation with support from specialist officers and local police teams.

Authorities added that they received multiple emergency calls late Friday reporting violent incidents involving threats, robbery, and vandalism across Edinburgh, resulting in injuries to five men.
