Three people were killed on Saturday in a knife attack in a park in the English town of Reading. A 25-year-old man was arrested after the act and the attack is being investigated as a terrorist offense.

The police initially stated that the knife attack did not appear to have any terror clutches, but changed on Sunday.

"Although the motive behind this horrific deed is still far from clear, the anti-terror police has taken over responsibility for leading the investigation," said Neil Basu, assistant police chief of the London Police at a press conference.
