Police on Saturday afternoon reported a group of protesters at the Glacis. The Saturdays for Liberty group has registered protests with the City of Luxembourg every Saturday for months to come.

A separate group, however, met at the central train station and made their way into the city under police surveillance. Some staged a sit-in on Boulevard Royal. Luxembourg City mayor Lydie Polfer last week had said that protests would only be allowed between the in Kirchberg. However, police didn’t break up the march, which had not been registered with city authorities.

Several hundred protesters finally convened at the Glacis causing traffic and public transport disruptions.

People were arrested trying to break through barriers into the city centre. There were also isolated incidents around the Place de la Constitution, which was under heavier protection.

The additional police presence came after criticism when protesters managed to on 4 December as well as vandalising the house of prime minister Xavier Bettel (DP).

On 11 and 12 December, police were out in , including a water cannon borrowed from Belgium. Protests had dwindled to around 500 people from an estimated 2,000 the weekend before. More than a dozen people were arrested.

Police meanwhile found “substantial quantities” of explosives, other arms and ammunition at the house of a 30-year-old man identified during the protests and suspected of throwing fireworks at police officers.

The public prosecutor’s office on Saturday said the army’s demining unit helped seized the explosives and an investigation has been launched by the anti-terrorism unit. The man has been presented to an investigating judge.

A man was previously arrested for sending to the prime minister and health minister Paulette Lenert (LSAP).
