Kajanto emigrated to Sweden from Portugal more than 30 years ago and had been married to his Finnish wife almost as long.
Swedish police have not commented on Kajanto's version of events, but they were prepared for the continuing violence.
"We are prepared for the worst case scenario," a police spokesman told the Independent. "And we have been every night since the first night."
At least 10 cars were set on fire in Rinkeby, a suburb close to Husby, where the trouble first began.
There were fires too in Jordbru, far south of the city centre.
It is the worst civil unrest in Sweden in modern times. More than 300 cars have been set on fire. At one point a police station in the north-west was set alight, but was quickly contained.
Five arrests were made yesterday, but only one person remains in custody.
On Thursday eight people were arrested in the Husby area. It is understood that the majority of those were not from the areas in which they were arrested, adding credence to the growing belief that the rioters are travelling from place to place, intent on causing trouble.
