TWO people were left injured following a violent altercation in Alloa town centre yesterday.
The alarm was raised just after 2pm, amid concerns for a member of the public.
Swathes of police then descended on the High Street, before entering the Salvation Army charity shop.
The culprit is thought to have been in possession of a blade and was later seen facing off with officers in the back of the shop.
Police had their batons drawn as they attempted to diffuse the high-pressure situation. 
A short while later, witnesses described seeing a man covered in blood spilling out onto the street.
Unconfirmed reports also suggest that an on duty police officer was struck in the face by a glass bottle.
The street was then sealed off with paramedics and riot police called to the scene.
An investigation is already underway and anyone with video footage or pictures of the incident is asked to contact officers on 101 or visit Alloa Police Station.
The Advertiser has been informed that police are not currently looking for anyone else in relation to the incident.
A spokesperson for Police scotland issued a statement last night which said: “Numerous police resources attended High Street, in Alloa...following a report of concern for a person.
“The incident has been concluded and one person has been detained in connection with this.
“We thank the public for their patience during this time.”
