A 100-strong deployment of officers has been working in the city, home to around 180,000 people, since Monday evening.
According to the city’s authority, an on-site construction worker tested positive for the mutated strain, which first emerged in Britain and is considered more infectious.
Four residential buildings were placed under quarantine and the residents there are being tested.
The Police officers are on site to ensure that they adhere to the quarantine measures.
The British strain or B117, is one of three variants of concern that have been identified within Germany by the nation’s agency for disease control, the Robert Koch Institute (RKI).
Earlier this month, RKI president, Lothar Wieler, reported that the B117 variant had been found in 13 of Germany’s 16 states and made up for just under 6 per cent of cases although he warned that that figure would likely rise further.
The German government recently boosted resources to laboratories for sequencing work in order to get a clearer picture of the spread of coronavirus variants in the country. (dpa/NAN)
