This was reported by Ukraine's Yellow Ribbon underground movement.
Activists note that the incident occurred at 61 Komsomolskaya Street.
The report also says that the city has a difficult situation with food — it is of poor quality and very expensive.
"There is a shortage of food of normal quality in the city. All imported goods are low-grade. This also applies to textiles. At the same time, prices in Mariupol stores are much higher than even in Moscow," the activists said.
On April 2, advisor to the mayor of Mariupol Petro Andriushchenko said that the occupation authorities are actively trying to settle Russians in the city from the European part of the Russian Federation.
"Russians are paid to come and live in the temporarily occupied Mariupol. That is, they receive money. With this money, they can buy furniture and make repairs. The occupiers issue warrants for apartments that they have recognized as ownerless. This is how the scheme works in Mariupol. And the occupiers are actively promoting it," Andriushchenko said.
According to Andriushchenko, Russians themselves are very supportive of the idea of moving to Mariupol.
On April 3, it was reported that massive cases of cholera among children were detected in the temporarily occupied Mariupol, which Russians are trying to hide with an undeclared quarantine.
