SAPS Western Cape spokesperson Lieutenant Colonel Andrè Traut said: "Organised Crime detectives supported by Public Order Police members embarked on a tracing operation last night. They arrested a 31-year-old suspect from Nyanga and seized a firearm with rounds of ammunition."
The firearm's serial number was filed off but was, however, sent for ballistic testing.
