A fourth person has been arrested over the alleged murders of Perth brothers Callum and Jake Robinson, who were killed during a surfing trip in Mexico.
Brothers Jake, 30, and Callum Robinson, 33, and their friend Jack Rhoad, 30, were surfing and camping in the Baja California region of Mexico, near Ensenada, when they disappeared on April 27.
Family and friends took to social media to ask for help finding them after they were unable to check into their Airbnb in Rosarito, near the US-Mexico border.
A fourth person has now been arrested in connection with the alleged murders, after the brothers’ bodies were discovered 10 meters deep in a well, Nine reported.
Callum and Jake Robinson (pictured) were last seen near the Rosarito and Ensenada region of Baja California, before their bodies were found in a well.
Authorities have not released any details of the arrested man.
The trio’s bodies were found weeks after they disappeared near their remote camp, and three Mexicans were arrested soon after.
Police were able to make the initial three arrests after one of the brothers’ cellphones turned back on and a local tower was pinged.
A woman was found in possession of the phone and some illicit drugs.
She was arrested along with two other men.
The incident is believed to have been a “robbery gone wrong,” with Mexican authorities alleging that the three men were shot in the head by locals who were trying to steal the tires from their truck.

Jesús Gerardo, the accused ringleader of the trio also known as ‘El Kekas’, appeared in court and will remain behind bars until his hearing in November this year.
Gerardo was arrested along with his brother Cristian Alejandro and his girlfriend Ari Gisel.
The brothers were commemorated by friends and family rowing at Sorrento Beach, north of Perth, this month, six weeks after their deaths.
Hundreds of people attended the paddle-out, heading out into the ocean on surfboards or boats and forming a circle with their oars in the air.
The Sorrento Surf Life Saving Club posted on its Facebook page about the ceremony.
“It will provide these communities the opportunity to come together to commemorate and remember these two wonderful children and show their support for their family,” the post said.
A large group of friends and family paddled out on a Washington beach in memory of Jake and Callum Robinson, who died during a surfing trip in Mexico.
“WA surfers, surf lifesavers and ocean paddlers will come together as one group as they paddle out to form a circle and remember Callum and Jake.”
Callum and Jake’s mother, Debra Robinson, paid tribute to her sons, along with her husband Martin, at their funeral in Sorrento, northwest of Perth, earlier this month.
They gave an emotional speech to the 800 grieving friends and family who witnessed the service, which was also livestreamed.
“We loved that Jake was curious, kind, happy and never judgmental,” Mrs. Robinson said.
“Callum always made a conscious decision to wake up and be positive every day.”
‘He saw a lot of funny things in life. We miss you beyond description boy Callum and Jakey please shine on us.’
“We miss you beyond description boy Callum and Jakey please shine a light on us,” said his mother Debra Robinson.
