It is a feeling we all know - the sudden, stomach-dropping moment you realize you've forgotten something important, from locking the door to turning the oven off.

So spare a thought for Dr Ben Carson who had just such a moment in the middle of a live interview on CNN while visiting his childhood home in Detroit.

In bizarre footage, Dr Carson is being interviewed about Donald Trump's visit to the city when he remembers his bags are missing.

Dr Ben Carson caused a stir on Saturday when he walked out of a live CNN interview after apparently forgetting his luggage

Carson was being asked by reporter Jeremy Diamond about Trump's visit to his hometown of Detroit when he suddenly remembered his bags

With outstretched arms and a stunned expression on his face, Carson exclaims 'oh, my luggage!' before mumbling 'hold on' as he walks away from the camera.

Prior to that moment, reporter Jeremy Diamond had been asking Carson why he brought Trump to his old home.

Carson said: 'I just wanted him to see what it was like, what the neighborhood was like. We also went through some of the more blighted areas of Detroit.

'When I was growing up it was a very prosperous city, it was once the most prosperous city in America and has unfortunately undergone some pretty awful things.

'In order for our country to be great again, every aspect has to be great, including our inner cities.'

Diamond then tries to ask Carson about what Trump has learned on the trip before he excuses himself and wanders away to speak with staff in the background.

Rather than waiting until the segment was done, Carson turned and walked out of the interview to track the luggage down

While Diamond continues speaking to the camera, the anchor back in the CNN studios appears flabbergasted at Carson's actions, but before she can put her shock into words he returns to finish the interview.

It is not clear whether Carson actually managed to track down his missing bags.

The former Republican presidential hopeful, now an adviser to Trump, was on hand to help out with the billionaire's latest appeal to the African-American community.

Carson had gone with Trump earlier in the day as he visited the Great Faith International Ministries church for a prayer service, where the nominee was seen swaying to the music with his eyes closed.

Trump said: 'For centuries, the African-American church has been the conscience of this country. So true.

'The African-American faith community has been one of God's greatest gifts to America and its people.'

Trump also vowed that if he was elected president he would bring jobs back to impoverished black communities.

Carson eventually returned to the interview, but did not say what the problem with his luggage was or whether it got sorted

He then visited Carson's bungalow-style childhood home in the city's southwest.

Trump and Carson chatted with the home owner Felicia Reese, who purchased the stone facing home in 1992, outside for a few minutes.

Trump joked that since Carson grew up there, the location was famous: 'This house is worth a lot of money!'

Manigualt told Reese: You're talking to a real estate genius!' and then said she would send Reese a copy of 'The Art of the Deal.'

As Trump left the area to return to the airport, he said: 'This is a great day!'

Asked what he thought of the day's visit to church and seeing Carson's home, he remarked: 'I loved it. I really liked it.'

Carson added: 'It was wonderful.'

This is not the first time that Dr Carson has caught media attention after leaving at an inappropriate time.

Back in January the former brain surgeon caused a stir after announcing he was returning home following the Iowa caucus rather than going to New Hampshire.
