A Cuban man has been arrested in Brazil for the alleged murder of art dealer Brent Sikkema, just days after he was found dead in his home in Rio de Janeiro.

Sikkema, 75, who founded gallery Sikkema Jenkins & Co., was discovered dead at an apartment he owned on Rua José Abreu Fialho in the affluent neighborhood of Jardim Botânico, the Civil Police confirmed to Artnet on Tuesday.

Authorities in Rio de Janeiro said in a statement that the suspect was arrested at a gas station between the cities of Uberaba and Uberlândia in the state of Minas Gerais.

He was identified after investigators with Capital Homicide Police analyzed security camera footage and obtained a warrant for his arrest. Artnet has contacted Gabriel, the security company used by Sikkema, for more information.

“We have no doubt that it was a premeditated crime,” said Alexandre Herdy of the Capital Homicide Police. What remains are doubts about the purpose of the crime, whether it was stealing or whether there was another motive.”

Sikkema’s lawyer has said that the suspect took jewelry and a value equivalent to R$180,000, between dollars and reais, which Brent would use to furnish a recently acquired apartment in Leblon.

Ultimately, the suspect was caught with support from Federal Highway Police and the São Paulo Civil Police.

“The police identified that the man was in São Paulo before committing the crime,” officials said in the statement. “It was to that state that he returned after the murder. From then on, he began to move around, being captured today by DHC.”

The suspect was identified as a 30-year-old man from Cuba by Capital Homicide Police in a separate statement. He was named by the Rio-based newspaper O Globo as  Alejandro Triana Prevez. Artnet has not yet confirmed the identity of the suspect.

Police are reported to be investigating whether Prevez had a relationship with Daniel Sikkema, identified by O Globo as the gallerist’s ex-husband. Daniel Sikkema is also reportedly from Cuba.

Friends of Sikkema told the Folha de São Paulo newspaper that Brent Sikkema had been to court trying to get permission to see the son the pair shared, born through a surrogate. Daniel Sikkema allegedly sought $6 million from Brent to see their son. Police reportedly confirmed such details to O Globo during a press conference.
