Police surround NY Courthouse and DC Capitol in case of Trump arrest

Police in major US cities are preparing for potential unrest in case ex-President Donald Trump is arrested this week as part of a hush-money inquiry.

Authorities in New York, Washington DC and Los Angeles are ramping up their law enforcement presence.

A Manhattan prosecutor may charge Mr Trump over how he declared a payment to a porn star to keep quiet about an alleged affair.

It would be the first criminal case brought against a former US president.

Steel barricades were being erected on Monday outside the Manhattan Criminal Court, where Mr Trump could be charged, fingerprinted and photographed if charges are filed this week, as US media widely anticipate.

Increased police presence has also been seen outside Trump Tower in the city.
