Police scale up response to east-west gang feud
BBCDetectives have scaled up their response to a series of deliberate fires in the Glasgow area which may be linked to several blazes and gun incidents in Edinburgh.
Police Scotland said six properties in the west of Scotland have been targeted in a week.
A number of arrests have been made in the east of the country following a spate of violent incidents and officers have seized weapons, drugs and cash.
The force also confirmed it had visited more than 100 properties and was reviewing over 700 hours of CCTV footage.
Videos claiming to show the fires have been posted online alongside warnings naming families that have been linked to organised crime.
The Edinburgh attacks have been ongoing for a number of weeks but on 3 April a house was deliberately set on fire more than 50 miles away in Cortmalaw Gardens, in the Robroyston area of Glasgow.
The following day a garage on Milton Road, Kirkintilloch was torched.
On 7 April properties in Gala Street and Ashgill Road, Glasgow, and Meadow Court, Stepps, were set on fire.
And on 8 April a business premises on an industrial estate on Wellington Road, Bishopbriggs, was targeted.
Det Chief Supt David Ferry, of the specialist crime division, said: "It is vital that we trace whoever is responsible for these reckless acts as soon as possible.
"While we believe these to be targeted attacks, the consequences could have been far more serious and I want to make it clear this behaviour will not be tolerated.
"Significant inquiries are ongoing in relation to all of these incidents, and we are utilising all available resources to identify those responsible and bring them to justice."
Officers in the west have also recovered a stolen vehicle.
Meanwhile, in the east the force said it had executed search warrants and made a number of arrests.
On Thursday two teenagers were arrested in connection with wilful fire-raisings.
An 18-year-old man was arrested and charged in connection with an incident which took place on the city's Hay Drive on 4 April; a wilful fire at a premises in Albert Street in the capital on 6 March; and the wilful fire of a vehicle in the Parrotshot area on 2 March.
He is due to appear at Edinburgh Sheriff Court later.
A 17-year-old male youth was released pending further inquiries.
Det Chief Supt Ferry vowed arrests would continue in the coming weeks.
He added: "I want to reassure the communities in the east and west of Scotland that we have a team of detectives working on this investigation and our continued action in recent weeks demonstrates our commitment to tackling this type of crime.
"We will continue to carry out additional high-visibility patrols and disruption activity and I would encourage anyone with any concerns to approach these officers, so we can take action."
The senior officer also urged anyone with information to contact police.
