According to the reports, the vehicles were found on fire at three different locations, on Müürivahe, Vene, and Olevimägi streets.

One of the blazing vehicles was located in front of the Tallinn Old Town College's (Vanalinna Hariduskolleegium) elementary school building on Vene street.

The PPA has verified the accuracy of social media reports of the blazes which had appeared soon after they were seen.

PPA: Two men detained

At around 1 a.m. early on Saturday morning the PPA received a report of a burning car on Müürivahe. The car in question was reportedly a Kia Ceed model.

A little under an hour later, the PPA received a second report of a burning vehicle on Vene, a street which Müürivahe runs into. This time the vehicle in question was a Mercedes.

At approximately 5 a.m. on the Saturday, a further report was received that a BMW X3 was ablaze, on Olevimägi, a short distance from Müürivahe and Vene.

Three more vehicles in the immediate vicinity of the burning cars sustained damage, the PPA said, though no more reports were made of any injuries sustained.

The PPA has responded to all reports and has now initiated an investigation to determine the circumstances behind the incidents.

The PPA noted that evidence collected at the scene and from security camera footage suggests the possibility of arson.

Based on initial evidence gathered, the PPA detained two men, aged 21 and 28, on Saturday evening, on suspicion of property destruction.

As per standard practice, the prosecutor's office has requested that the first-tier Harju County Court detain the suspects.

Further details of the case will be clarified during criminal proceedings, the PPA added.

Two suspects in detention for up to two months

Harju County Court subsequently agreed with the prosecution's assessment and has taken the pair into custody, for a period of up to two months.

District Prosecutor Diana Helila said: "Since the investigation to clarify the circumstances surrounding the case is still in its early stages, the PPA are working with different investigative version of events, so at the moment it is not yet possible to say what the motive might have been."

Since the two men could potentially evade criminal proceedings and commit new crimes if left at liberty, the detention is still necessary, however, the prosecution said.

"Aktuaalne kaamera" reported that the individuals detained are both citizens of Finland.

As to ERR's question to the Internal Security Service (ISS) on whether the incidents may have been orchestrated and planned by Russian agents, the ISS, known in Estonian by the acronym Kapo, said that the PPA was dealing with the matter and no further comment could be provided.

Interior Minister Lauri Läänemets' (SDE) car was vandalized early on this year; the ISS put that incident and damage done to another vehicle, belonging to a journalist, down to Russian secret service activities.

Editor's note: This story was updated to include the approximate times and other details surrounding the incidents, including the detention of two suspects.
