The Muslim teenager arrested for bringing his home-made clock into school was a ‘weird little kid’ that could have a future in crime, according to one of his former teachers.

Retired Sam Houston Middle School teacher Ralph Kubiak said that 14-year-old Ahmed Mohamed was a troublemaker in his younger years.

‘He’s one of those that could either be CEO of a company or head of a gang,’ Kubiak told the Dallas Morning News.

The teenager was arrested two weeks ago after teachers at MacArthur High School mistook a homemade clock for a bomb.

Fourteen-year-old Ahmed Mohamed, who made headlines after bringing a homemade clock to school that was mistook for a bomb, was a troublemaker in middle school, teachers say

When Mohamed's clock (pictured) started beeping in class, police were called and he was arrested. No charges were filed, but the teen was suspended for three days

The school's principal called police, and Ahmed says he was arrested, handcuffed and taken to juvenile detention.

Ahmed wasn't charged - but he was suspended from school for three days. His father has since removed him from the school district.

The clock debacle wasn’t the first time Mohamed raised eyebrows in the school district. In middle school he racked up a number of suspensions and once made a homemade remote to turn off one of his classroom projectors.

The Irving School District investigated claims of anti-Muslim bullying from staff members and students about a year after Mohamed arrived at the school, knowing almost no English.

Mohamed claimed his classmates called him ‘ISIS boy’ and ‘bacon boy’ and said his teachers told him he couldn’t pray in school.

The teen’s disciplinary record is confidential, but peers and former students said that some incidents were blown out of proportion.

Mohamed reportedly brought several versions of his homemade clock to school in the past without a problem.

And family friend Anthony Bond said that one suspension came after the teen was found blowing soap bubbles in a bathroom with his cousin.

‘Kids are kids,” Bond told the Dallas Morning News. “He was a little boy in a new environment, and they were acting out.”

Since Mohamed's clock debacle, he been touring high-profile locations around the country, including the White House and the annual Google Science Fair. Left he is pictured at New York's Social Good Summit and right with Queen Rania of Jordan

Teachers, however, say that Mohamed was suspended several times while at Sam Houston Middle School

After an incident in which Mohamed was suspended for defending himself in a hallway fight, Bond wrote a letter to the district to get the boy’s suspension overturned.

Earlier this week, Irving Mayor Beth Van Duyne claimed that Mohamed's failure to comply with officers was the reason he was detained.

'In my own conversations with the police is that he was not forthcoming with information, but I just think common sense prevails,' Mayor Duyne said according to KDFW. 'Does it make sense? And if not, why?'

Earlier this week, Irving Mayor Beth Van Duyne backed the school's decision to arrest Mohamed

Meanwhile Texas Municipal Patrolman's Association president Heath Wester said he believed Ahmed took the device into school as a publicity stunt.

Speaking to Rawstory, Wester said: 'I think his intent was to see how far he could get with the device and to see what kind of alarmant he could get.

'And as you can see now, he's got what he asked for. He's gotten that alarmant. He's gotten that excitement or whatever he was trying to get. He got it.'

An Image of a handcuffed Ahmed being escorted out of MacArthur High School, in Irving, went viral after teachers claimed the device 'looked-like a bomb'.

Mayor Duyne, who previously made headlines for voicing her fears that Islamic Sharia law was coming to Dallas, said Ahmed's family had not responded to the city's request to have records of the incident released.

Among the outpouring of sympathy for the boy was a message from Barack Obama inviting him to bring his clock to the White House.

The Texas high-school freshman's parents withdrew him and his siblings from their Irving Independent School District schools last week.

Their father, Mohamed El-Hassan Mohamed, says the family is still deciding where to send the children to school.

Mohamed has since been touring high-profile locations around the country, including the White House and the annual Google Science Fair.

He stopped at the Social Good Summit in New York City on Sunday and made a stop at City Hall on Monday, according to the New York Daily News.

There he received a city proclamation honoring his work in tech. The proclamation called him a role model for young people who want to pursue careers in math, science and engineering, and improve the world for future generations‘

Mayor Duyne spoke about Ahmed's arrest during a meeting of the Arlington Republican Club.

She reportedly said that the teenager was more cooperative with the press than the police.

'He told a lot more to the reporters than he ever told to the police,' Mayor Duyne told Blaze TV

'There's a problem with that.'
