The news came as some people expressed concern online about the first day of a month-long pedestrianisation of Tērbatas street in Rīga which may have proven to be too popular for its own good. Many people posted pictures of large crowds gathered in the street with individuals packed close together and few signs of face masks being used, though this is not a mandatory requirement.
Others however said that in general people were maintaining some distance and welcomed the relaxed festival atmosphere on what is normally one of the Latvian capital's busiest streets.
Health Minister Ilze Viņķele called on members of the public to enjoy themselves in a responsible manner.
"It is nice that Tērbatas Street has been given over to pedestrians. But. Dear Rigans and guests - it is not safe to listen to concerts in crowds," she said, adding that careful thought was required to make sure such events do not become points of COVID-19 contagion.
Ir jauki, ka Tērbatas iela nu ir atvēlēta gājējiem. Bet. Mīļie rīdzinieki un viesi - pūļos klausīties koncertus nav droši. Domājam līdzi gan skatītāji, gan rīkotāji, lai ballīte nesanāk īsa un ar Covid piesitienu.— Ilze Viņķele (@Vinkele) July 17, 2020
That advice was followed up Saturday morning by an announcement from Interior Minister Sandis Ģirģens that Saturday evening's concerts would be cancelled and more police would be on hand to monitor physical distancing.
Publiska pasākuma organizators uzņemas atbildību par tā norisi un uzraudzību. Pēc vakardienas Tērbatas i. pasākuma pašvaldība šodien atceļ koncertus, VP nāks palīgā PP un pastiprināti patrulēs, kā arī reģistrēs materiālu un izskatīs administratīvo atbildības pakāpi organizatoram.— Sandis Ģirģens (@SandisGirgens) July 18, 2020
