The Greek pilot who admitted killing his British wife staged the house raid to stay out of prison, police said.
It is alleged Babis Anagnostopoulos also broke a window, hanged his dog and tied himself up so he could be free to look after his baby daughter.
He is accused of removing a sim card in a security camera to try to fool police that Caroline Crouch, 20, was murdered by robbers.
The helicopter pilot, 33, appeared in an Athens court on Friday wearing a bulletproof vest and handcuffs.
He had claimed armed raiders broke into his home in Glyka Nera, Athens, on May 11.
He said the robbers strangled his wife in front of their 11-month-old child and stole £13,000.
His account started to unravel when police found no evidence of other people having been in the home.
Evidence from Caroline’s smartwatch is said to have revealed she died earlier than Anagnostopoulos had claimed.
She had been suffocated.
Data from his phone allegedly showed that he had been moving around when he claimed he was tied up, police added.
Detectives flew to the island of Alonissos on Thursday, where Anagnostopoulos was mourning Caroline.
Minutes before they arrived he was snapped hugging mother-in-law Susan Dela Cuesta at the victim’s grave.
According to one report, Greek police chief Petros Tzeferis said Anagnostopoulos told them: “I tied myself up.
“I did everything because when I realised I killed her, I thought of my child.”
He faces charges for two crimes and two misdemeanours, including intentional homicide and animal abuse, reports claim.
on Friday his lawyer Vassilis Spyrou said his client told him: “I am sorry. I want to be punished for what I did.”
