Four suspects have been arrested in the alleged murder of a Venezuelan opposition leader and mayor who was stabbed to death at his home early Sunday morning.

Officials said the body of Enrique Franceschi, 34, was found at 5 a.m. by a maintenance worker, according to El Universal.

"According to preliminary information, Franceschi's lifeless body was found during the morning hours on Sunday, July 20, with multiple wounds caused by a knife, inside his home located in Rio Caribe," the prosecutor's office said, according to Fox Latino.

Preliminary reports revealed a commando-style group entered Franceschi's home and stabbed him to death, according to El Universal.

His family was not at home at the time because they were in Caracas. Franceschi lived with his wife, 5-year-old son and grandmother.

Franceschi was a member of Mesa de Unidad Democratica (MUD), or the Democratic Unity Roundtable, an alliance in opposition of socialist party of the Venezuelan president, and had been mayor of Arismendi, in the state of Sucre, since December 2011, according to Fox Latino.

The country's interior minister, Miguel Rodriguez Torres, announced the arrest of four individuals in connection with the crime: Fran Rodriguez Jimenez, 20, Luis Jesus Velazquez, 19, and two other males aged 15 and 22.

Torres said political motives had been ruled out and that Franceschi apparently knew some of the individuals since it appeared those who entered the home did not use violence.

"It has been able to be determined from statements of the involved persons and witnesses and those who knew the mayor that Fran Rodriguez Jimenez and Luis Jesus Velazquez were ... very close friends of Mayor Franceschi," Torres said, according to Fox Latino.

"On behalf of all mayors of Venezuela, our most sincere condolences for relatives and friends of Enrique Franceschi. Lamentable tragedy," tweeted Antonio Ledezma, the mayor of Caracas and also an opposition leader, according to Fox Latino.
