Green Action president Tomislav Tomasevic said they demanded the resignation "because Minister Dropulic is a politician who has been in the biggest conflict of interest in Croatia for years."

"How can we believe her that everything is in line with the law when she is a stockholder in the company which designed the construction project in Varsavska Street," he asked.

Demonstrators first met at 7 pm near the construction site for a ramp to an underground garage in Varsavska Street to show their dissatisfaction with the construction works, which they claim rob citizens of public space, but police would not let them near, prompting the demonstrators to once again demand the resignation of Interior Minister Tomislav Karamarko.

Teodor Celakoski of the Right to the City distanced himself from several hate speech incidents involving members of the Bad Blue Boys football fans' club.

The demonstrators once again demanded the resignation of Mayor Milan Bandic as well.

Tomasevic announced a new rally for Monday at 7 pm.

Press estimated that today's protest, the third in a row, brought together between 1,000 and 2,000 people. They dispersed by 8.45 pm.

More than 150 activists, politicians, lawyers, journalists and citizens were arrested and held in custody on Thursday because of their participation in a peaceful protest against the project in the historic centre of Zagreb. They were arrested for offering passive resistance to the continuation of construction on a ramp to a private underground car park in Varsavska Street.

Yesterday, the demonstrators protested in front of the headquarters of both the HDZ and the SDP.

Also yesterday, the European Greens (EGP) condemned the arrests, stressing this was not appropriate behaviour for a country in the process of joining the European Union.
