After the attack, St. Petersburg police began to travel 300 times more often for checking the ownerless objects. In March, they went to check no more than 2-3 times a month, now-up to 20 times a day.
According to Fontanka, over the past 6 days, only the police made at least 120 departures after the calls of citizens about suspicious objects. In addition, on average 6 times a day, the Ministry of Emergencies arrive for false mining. Most messages from the Admiralty, Central, Moscow and Petrograd districts.
At the same time, the specialists had to check the plush elephant and the gnome, a toy machine, a bag with glass jars and one homeless. However, the main reason for the checks are ownerless bags, backpacks, boxes and just household garbage.
The peak of calls about the ownerless objects came on April 4 and 6, the day after the attack in the subway and on the day of the detention of possible accomplices of the alleged suicide bomber.
In addition, from April 4, the St. Petersburg metro stations were urgently closed 11 times.
