Officers in Poole are appealing for witnesses and anyone with information to come forward after reports of a man threatening members of the public with a knife – with one man being arrested.
Dorset Police was called to the incident in Sterte Avenue in the Holes Bay area at 6.49am this morning.
Officers, including armed police, attended and searched the area. The NPAS helicopter also assisted in the search.
Nobody was injured during the incident.
A 29-year-old man, of an unknown address, has been arrested relation to this incident and is helping officers with their enquiries.
A man has been charged with murder after a stabbing in Bracknell. 24-year-old Aleksandrs Vasiljevs died following an incident at a property in Appledore in Great Hollands last month. Ivan Svatovskij who's 31 and of the same address, is charged with murder.
Police are warning people about carrying small items that could be seen as a dangerous weapon.
It comes after a 21-year-old man was given a fine of £175 after police found he was carrying a small knife on a keyring.
The knife was under 3 inches long but it was said to be dangerous enough that the male was charged with possessing a knife blade or sharp pointed article in a public place.
PC George Rabczak at Wiltshire Police said, "The male argued that the knife was under three inches and could not do any damage.
"This is clearly not the case as the sharp-pointed tip and jagged edge could cause serious injuries if used in a violent manner.
"I would urge anyone to think carefully about what they carry in public as anything which could be used to cause harm could result in you getting arrested and charged."
A man carrying a knife forced his way behind the counter of a petrol station in Brockenhurst and stole several hundred pounds.

He also had a tattoo or mark on the left side of his neck.
Officers from Lyndhurst CID have released the CCTV images of the suspects and want anyone with information on the man to contact them on 101.

Police have issued an e-fit of a man they want to speak to after a 16-year-old girl was robbed at knifepoint in Hastings.
The theft, which happened near the Spar store in St Helens Down on Monday evening, is being linked to two other robberies in the town.
Det Serg Paul Graham said: "We believe this man is local to the area. He is described as white, about 30, slim with short brown or dark hair and about 5' 5" to 5' 9". When he approached the girl in the latest robbery he was wearing a black zip up jacket and a black rucksack."
The teenager was approached by the man at about 6pm. He demanded her phone and when she refused he showed her a knife and grabbed her two carrier bags of shopping.
Det Sgt Graham added: "The girl was obviously shaken by the incident but otherwise unhurt.
"We think the man is linked to two other robberies that took place near convenience stores, all within a few hundred metres of each other. On each occasion the people had been shopping.
"They both happened on Saturday, the first in Victoria Avenue at 7.30pm where the man stole a mobile phone and handbag, the second at 10.30pm at the junction of Victoria Avenue and The Ridge when he demanded a woman hand over her handbag, but she refused."
Anyone with information is asked to call police on 101 quoting Operation Zephyr or the independent charity Crimestoppers anonymously on 0800 555111.
