London's Victoria Coach station was evacuated early morning on Tuesday as Metropolitan Police announced that it is checking a suspicious package on the premises.
"A suspect package is being checked out," a police spokesman said, according to BBC reports.
The evacuation came just hours after at least 22 people were killed and more than 50 were injured in an explosion at a concert by famous United States singer Ariana Grande in Manchester on Monday.
The explosion occurred at the end of the concert, and according to two US officials, a suicide bomber was suspected to be behind the attack.

UK Prime Minister Theresa May said that the incident was being treated as a terrorist attack by police authorities. If it is confirmed as one, this would be the deadliest militant attack on Britain since suicide bombings on London's transport system in July 2005, which had killed 52 people.
Police reportedly believe that the attacker died at the venue after detonating the bomb. No terrorist organisation has claimed responsibility yet.
Security has been increased throughout the country, and UK politicians have also suspended their campaigns for the upcoming general elections, in wake of the attack.
