“The suspect was arrested early on Friday morning following witness reports of a man fleeing the scene. One witness was able to give a very detailed description,” local police officer Fitzroy Frederick said to news agency TT.

The arrested man, according to Frederick, bears a close resemblance to the drawing that the police were able to make from witness testimony.

The 32-year-old man has been interrogated but denies the charges.

The police investigation is continuing with DNA testing of the suspect and an examination of the evidence accumulated at the murder scene.

“We would also like to forward our condolences to the couple’s relatives and the Swedish people. They should know that we are doing all that we can to see that the murderer is served justice,” Frederick said.

The couple, identified in several media sources as 62-year-old Anna Sundsvall and 73-year-old Åke Alsson, were found murdered in their holiday home on Thursday morning.

The couple had bought the home four years ago and according to local police divided their time between Sweden and Tobago. The house lies on the south-western tip of the island of Tobago in the picturesque area of Bon Accord.

The alarm was sounded by a security guard patrolling the area when he heard screams.

Police arrived at the scene with emergency staff and found Sundsvall already dead. Alsson was barely alive and was rushed to Scarborough Regional Hospital where he later died.

The circumstances indicate that the murders occurred in connection with a burglary. A safe was found bust open in the couple’s house.

According to the newspaper Trinidad & Tobago Express, 420 people have now been murdered in the country so far this this year, four of whom on the island of Tobago.
