BOGOTA (REUTERS) - Demonstrators took to the streets for a second night in Colombia's capital Bogota on Thursday (Sept 10) to press ahead with protests against police brutality that have erupted in violence and taken nine lives so far.

The demonstrators were protesting the death this week of law student Javier Ordonez, 46. A widely-shared video filmed by Mr Ordonez's friend showed the father of two being repeatedly shocked with a stun gun by police. He died later in a hospital.

Some 300 protesters gathered once again on Thursday afternoon outside the police station in Villa Luz, where Mr Ordonez was taken before his death and which was heavily damaged on Wednesday.

"How many are you going to kill today," screamed barista Alejandra Pulido, 25. "The authorities that should protect us are killing us!"

The crowds chanted, "Pigs, pigs, pigs!", as police officers with riot shields stood in front of a statue of the Virgin Mary.

A number threw stones at the assembled police while others spray painted graffiti on their riot shields.

Since the protests started on Wednesday in Bogota and the satellite city Soacha, at least nine people been killed while hundreds of civilians and police officers have been injured.

Bogota Mayor Claudia Lopez said people should return to their homes by evening, to ease tensions.

"Although there is no curfew in Bogota, we ask that by no later than seven o'clock, all those who can, please stay at home," Ms Lopez said in a Facebook Live broadcast.

Yet as 7pm approached, demonstrators threw rocks and bottles at police, attacking the windows of the station with an uprooted road sign and setting the front of the post briefly alight.

Police responded with tear gas and flash-bang grenades, sending protesters running.

More than 60 people suffered gun-related injuries, the mayor's office said. Ms Lopez compared the unrest to the worst days of Colombia's armed conflict.

The video of Mr Ordonez shows him pinned to the ground by police officers and subjected to successive electric shocks early on Wednesday as he begs, "please, no more".

Police say Mr Ordonez was found drinking alcohol in the street with friends, in violation of coronavirus distancing rules. He was taken to a police station in western Bogota.

Two officers suspected of involvement in the alleged abuse of Mr Ordonez have been suspended pending an investigation, the government has said.

Mr Ordonez's family called for justice and peaceful protest.

"He was murdered by the police officers," his sister-in-law, Ms Eliana Marcela Garzon, told Reuters. "We don't want (deaths) in a country already full of conflict, we want justice."

Police reform is needed, Ms Garzon said, especially for the future of children like her now-fatherless nephews.

"I don't want them to grow up feeling like there isn't justice in this country," she said. "I want them to grow up knowing laws are followed."

President Ivan Duque has said abuse of authority should not be tolerated, but the government called for Colombians not to "stigmatise" police officers and appealed for calm.

Bogota's police will be reinforced with 1,600 more officers, more than half of whom will come from other regions, and 300 soldiers, the defence ministry said.

An effort by labour unions earlier this week to revive last year's mass protests against Duque's economic and social policies garnered a tepid response amid ongoing coronavirus restrictions.

But Mr Ordonez's death could fuel renewed outrage against the police, who were widely criticised last year after a teenage protester was fatally injured by a riot squad projectile.
