Ilkeston Police officers have described an altercation between two men in the town as an 'isolated incident'.
A response was directed to Wilton Place in the town and arrived within six minutes of officers receiving a call just before 11:30am on Friday 15th August.
One man, in his 50s, sustained a minor arm injury, and was taken to hospital for treatment, with an injury thought to have been caused by a knife which was subsequently recovered.
High visibility patrols have been carried out with two cordons set up around the time, one soon removed, another staying in place into the afternoon.
A statement said the two men involved were known to each other.
The update comes after officers were called to reports that a man had been injured during a separate altercation in the town on Thursday 14th August, which occurred around 12:15pm and involved three men.
The victim was found to have suffered a punch to the mouth. Ambulance staff spoke to the man who was found to have suffered a minor injury, but he refused further care.
Enquiries have been ongoing into the identities of those involved in the incident.
