A star Philadelphia high school football player was shot dead by his twin brother, say police.

Fayaadh Gillard, 18, was arrested for his alleged involvement in the death of his twin brother, 18-year-old Suhail Gillard, on Sunday.

NBC Philadelphia reports the Fayaadh is accused of shooting Suhail once in the chest in their father's apartment at the Liberty Towers in the Overbrook neighborhood, in Philadelphia, around 5.20pm.

The two brother's are said to have been playing with the gun when it accidentally went off.

Suhail was taken to Lankenau Medical Center and pronounced dead four hours later when he succumbed to his injuries.

Initially, Fayaadh told police that his brother was shot by a different gunman at a store.

But he was arrested Monday and charged with murder, possession of an instrument of crime, unsworn falsification to authorities, and obstructing justice for reportedly lying to police.

The Gillard brothers attended Mastery Charter North High School as seniors and were star players on the football team.

They were recently given first-team All-Public honors and Suhail was a three-time All-Public League player, as well as a member of the track team.

Hasan Ford, the brother's uncle, told ABC News that the shooting was accidental and are confident that there was no foul play involved.

'This was an accident. Fayaadh is an excellent and great kid just like his brother,' Ford said.

'They were our greatest pride and our greatest joy. They were the ones with the most potential of our lineage.'

Ford did not reveal how the teenagers gained access to the firearm, but said that they had not 'dealt with guns prior to this incident.'

John Davidson, the assistant principal and head football coach at Mastery Charter School Lenfest Campus, said the incident has unsettled the community.

He says Suhail was a 'scholar athlete' who was receiving several college offers.

Davidson: 'We all admired his work ethic, his commitment to the game and his strive to always be better'

Davidson said: 'He was a hard worker -- on and off the field. He was one of the players that I would love to coach again. We all admired his work ethic, his commitment to the game and his strive to always be better.'

'As a school, we've rallied together to support one another as well as his family in this tragic time,' he continued.

'He was a rock for us.'

A man who identifies as another football coach , Mickey Grace, mourned Suhail's death on Twitter.

'It’s with grieving hearts that we inform you of the untimely passing of our beloved brother, Suhail Gillard. He was the most respected and hardest worker Mastery ever had the honor and privilege to put a jersey on. Rest well #Agent4 4ever.' he wrote.

James Sadler, who said he taught Suhail in seventh grade, said: 'Yesterday I received devastating news that a former student of mine died.'

'Above all, Suhail was human. He was hilarious, kind, and incredibly determined.'

In response, the school hosted a balloon releasing ceremony for Suhail at Penn's Landing, the park where Mastery Charter High School will host senior graduation in the upcoming year.

The school is also planning to present the boys' mother with a jersey and trophy in honor of Suhail.

'He's been in our school since the seventh grade and his mom has been a part of our fabric since he's been here,' Davidson said.

'We're a very small school with a strong family atmosphere. We're trying to heal, but it's a continuing process and it's going to go on for some time.'

A memorial was erected near the school's entrance of his football jersey number, flowers and photos of him.
