UK police make another arrest in parliamentary attack investigation

Police have arrested a 30-year-old man in the central English city of Birmingham in connection with last week's attack on parliament, "on suspicion of preparation of terrorist acts", the Metropolitan Police said on Sunday, Reuters reported.

The police said in a statement they had arrested 12 people since Wednesday's attack when British born Khalid Masood killed four people and was himself shot dead. But nine had been released with no further action, the police added.
