London police arrested 12 suspects in connection to the terrorist attack that took place on Saturday night that killed 7 people and injured 48.

The arrests took place in east London and police say in a statement they are searching a number of other addresses in that area.

The police did not release the names of the people who were arrested.

The arrests are in connection to an attack that started around 10 p.m. local time when a van struck pedestrians on London Bridge. The van then drove to an area near London Bridge called Borough Market, where three men left the vehicle and stabbed a number of people, police said.

Police shot and killed the three suspects when confronting them at Borough Market.

The attackers were wearing fake suicide belts as well, London police said in a statement.

The terrorist attack occurred roughly two weeks after a terrorist bombing at an Ariana Grande concert in Manchester, England killed 22 people. London was also the scene of a terrorist struck numerous pedestrians with his car on Westminster Bridge in March killing five people and injuring around 50.

The attack occurred only five days before Britons head to the polls for national elections on Thursday.
