Addresses were evacuated on Saturday after officers found what they believe to be an improvised explosive device.
Police issued the following statement:
"We were called at around 10.15am on Saturday (May 16th) to reports of an affray involving several people on Livingstone Road.
Officers attended but those involved had made off.
A short time later officers stopped a man believed to have been involved in the affray. He was found to be in possession of knives, machetes and class A drugs.
Officers also found an item in his possession which looked as if it may have been a home-made explosive device. As a precaution a controlled explosion was carried out and a number of houses on Reads Avenue were evacuated.
Reads Avenue was closed for a short time but has since reopened.
A man, aged in his 40s and from Blackpool, was arrested on suspicion of affray and remains in police custody.
Two further men have since been arrested. They are a 19-year-old man arrested on suspicion of affray and an 18-year-old man arrested on suspicion of drugs offences. Both remain in police custody."
