Sussex Police are thanking the public for their patience following the incident in Durrington yesterday (July, 12).
Officers were called to reports of a domestic incident at an address in Rochester Close shortly after midday.
On arrival, police discovered a man in the garden in possession of a sword.
Police have confirmed the man was wearing body armour and ski goggles.
Following several hours of negotiations, a cordon was set up to contain the area for public safety.
At around 7.20pm, officers secured the man and the sword.
The man was tasered, police say this was due to non-compliance.
The 26-year-old man was arrested on suspicion of affray, assaulting a police officer and criminal damage.
He remains in custody at this stage and is due to undergo a mental health assessment.
Police say they would like to thank the public for their patience and understanding.
Chief Inspector Miles Ockwell, district commander for Adur and Worthing, said:
“Our primary objective was to negotiate with the man to try and bring the situation to a safe and successful conclusion, and to ensure the safety of the man himself, the public and the police.
“Due to the nature of the incident, it required a number of highly trained officers with specialist skills such as firearms and riot officers, a dog unit and PCSOs to manage and contain the area for public protection.
“The use of a helicopter was necessary for us to safely view the actions of the man, who for periods of time was in possession of a lethal weapon.
“We also used a drone while the helicopter refuelled.
“We are mindful that this incident will have caused concern for many people in the area and we would like to thank everyone for their patience, support and understanding while it was being dealt with.”
