The teenager was arrested at premises on the Gransha Road on Tuesday afternoon.
He was released on bail pending further enquiries.
Police confirmed that CS spray, generally used by officers to control aggressors in situations where lethal force is inappropriate, was used during the incident.
It can cause streaming eyes and a burning sensation.
Figures on the PSNI's use of the substance noted 479 cases in 2008/9, including 28 involving members of the public aged 17 and under.
The Police Ombudsman Dr Michael Maguire, is investigating the incident.
His spokesman said: "The Police Ombudsman's Office is aware of an incident which took place on Tuesday during which police are alleged to have used CS spray on a 14-year-old boy.
"The matter is now being independently examined by investigators from the office."
The Ombudsman used to automatically examine the use of CS spray, but stopped doing so a few years ago.
