“We are taking this matter extremely seriously and are using all resources available to us. We are keeping an open mind to the motive of the attacker and we won’t speculate further at this stage.

“We’re examining CCTV and speaking to witnesses. I’ve been speaking to people this morning, and so I know just how concerned they are and that people are after answers.

“We are determined to get those answers as soon as possible, and I’d urge the community to work with us and to avoid any speculation at this stage.”

Extra officers will be in the area today to speak to the community and to provide reassurance.
