In the event that former President Donald Trump is detained this week as part of a hush-money investigation, police in key American cities are ready for potential violence.
Authorities are increasing their law enforcement presence in New York, Washington, DC, and Los Angeles.
Regarding allegations that he bribed a porn actor to stay quiet about the alleged affair they had, a Manhattan prosecutor may press charges against Mr. Trump.
It would be the first time a former US president had been charged with a crime.
Steel barriers were being built on Monday in front of the Manhattan Criminal Court, where Mr. Trump might be charged, photographed, and fingerprinted if charges are brought this week as is largely expected by the US media.
Also, there has been more police presence in the area around Trump Tower.
A police source told CBS, the American partner of the BBC, that every member of the New York Police Department (NYPD), including plainclothes detectives, has been ordered to wear their full uniform on Tuesday and is being put on standby to mobilize.
