A FORMER terror suspect with a string of convictions landed a job at Heathrow after bosses failed to carry out any background checks.

Sun investigators watched as Mohamed Abdullahi Mohamud, who is also a sex offender, was allowed access to the runway and baggage handling areas.

The Somali, 31, who uses 17 ­aliases, got a kitchen porter job through an employment agency and was given a security pass when he started work last Monday.

Simple checks would have shown he has served five years in prison in total since 2003. He has racked up 14 convictions for 21 offences including threats to kill, robbery, assault and money laundering.

Terror cops have quizzed him ­several times amid concerns he may have been radicalised after he told a probation officer he hoped she would be taken to Syria and chopped up by IS.

He also faced terror charges over alleged bomb hoaxes two years ago, but the case was dropped due to insufficient evidence.

Mohamud, of Hounslow, West London, was also put on the sex offenders register in 2015 after he was convicted of sexual assault.

He revealed the Heathrow security breach after filming himself airside — but insists he is not an extremist.

He told The Sun: “These security procedures are a disgrace and need to be exposed. I’m not an extremist or terrorist, I love Britain and want to protect it.

“I can’t believe how close I can get to the planes and luggage. I can’t believe staff at Heathrow don’t get checked. It’s crazy.”

He was issued a temporary security pass without full checks being done, which take about four weeks.

Mohamud was employed through SM Global Consultancy Ltd and worked for five days in Terminal 3 last week, but has now been sacked.

Heathrow said no security breaches were made and Mohamud was “constantly escorted by a permanent member of staff” and searched before being allowed into certain areas.
