More than 90 protesters have been arrested in demonstrations during US President Donald Trump’s inauguration in Washington.

“We have arrested approximately 95 people,” said Metropolitan Police Department spokesman Lt. Sean Conboy on Friday. They were arrested for “vandalism and destruction of property.”

Around 500 people, wearing masks, marched through the city’s downtown with some of them smashing windows and blocking traffic.

Officers in riot gear used pepper spray, tear gas and stun grenades to disperse the crowd, some of whom were armed with crowbars and hammers, according to authorities.

Two officers were injured while they were trying to arrest some protesters, police said.

The protesters chanted anti-Trump slogans and carried signs, reading “Make Racists Afraid Again,” a play on the New York businessman-turned-politician’s “Make America Great Again” campaign slogan.

Some other protesters were carrying sings of support for Democratic presidential nominee Hillary Clinton who was defeated by Trump in November 8 election last year.

“The message I want to send is that Trump does not represent this country. He represents the corporate interests,” said Jessica Reznicek, a 35-year-old Roman Catholic aid worker from Des Moines, Iowa.

The US Secret Service, Washington police and other law enforcement agencies used nearly 28,000 officers to tighten security in a roughly three-square-mile (7.8 square km) of downtown Washington.

Trump was sworn in as the 45th president of the US at Capitol Hill, pledging to embark on “a great national effort” to rebuild the country.

In his inaugural address, Trump vowed that he would take a decision that puts “only America first.”

Before he took the oath of office, protesters descended on Washington with a message for him: “You’re not my president.”
