Steve Johnson also says he saw a second shooter 'wearing red shorts'

Says her injuries were inflicted by small-calibre weapon and not AK-47

The nursery nurse says her attacker was not extremist Seifeddine Rezgui

Three survivors of the Tunisian beach massacre have come forward to insist there was a second gunman during the murderous attack which left 38 dead, as police announce they have made several arrests.

Kirsty Murray and Steve Johnson, who were in entirely different parts of the complex, as well as Mr Johnson's friend Michael Perry have all now said that they believe Seifeddine Rezgui was not the only gunman last Friday.

Retired police officers Mr Johnson and Mr Perry have both described how they saw a second man shooting at tourists as they hid on the third floor of the hotel.

Both claim this man, dressed in red swimming shorts, was holding an automatic rifle and shooting the tourists.

The eye witness's account suggests that the gunman was not a 'lone wolf' as current reports state.

Their account is backed up to an extent by Kirsty Murray, who was shot in both legs by a man she says was not Rezgui in a hotel corridor.

But she says it was not an automatic rifle, like Rezgui was using, but a smaller weapon.

Her father Neil said: ‘She believes there were at least two gunmen because she was shot at close range with a handgun.

'Both her and her fiancé have said there was more than one gunman. One person is not capable of doing that much damage anyhow.'

However, there is no actual evidence there was a second man shooting tourists during Friday's massacre, in Sousse.

Witnesses quoted in The Guardian described seeing a man in red shorts trying to shoot at Rezgui after he threw a stun grenade was thrown in a group of men.

'He was trying to fire it at the guy, but it was like he didn’t know how to get the safety catch off or something', Aymen Khalifa Belhaj told the newspaper.

Instead, Tunisian police are conducting a nationwide hunt for accomplices they believe helped with weapons and logistical support, but 'did not participate'.

Interior Minister Mohamed Najem Gharsalli has said arrests have been made, but wouldn't be drawn on the number.

He did confirm that everyone arrested is Tunisian, adding the investigation remained in its early stages.

Yet Mr Johnson and Mr Perry are unequivocal about what they saw - and were even told by a high-ranking policeman that the man they described was 'dead as well'.

Mr Johnson, of Leicester, said he watched events unfold from the third floor after escaping from the beach.

'There was gunfire going during that time and by the time we had got up to the third floor and were looking down, we saw a number of bodies on the terrace and the steps and saw another guy - because my colleague had seen the man in the black shorts and shirt on the beach shooting people and now we have got a guy in red shorts with a gun walking down through the terrace and down by the pool and it looked like local people running away from him,' he told BBC World at One.

Asked if he was sure there were definitely two attackers, he said: 'What I am saying is the one on the beach - definitely. The one by the pool? Who else would have a gun in swimming shorts walking down in that sort of environment and why were people running away from him?'

Mr Perry added: 'We looked out and below us by the pool I could see three dead bodies.

'Then I saw young man who was bare chested and wearing bright red shorts, carrying a large assault rifle, moving from the building towards the beach.

'He was stooped looking around and pointing his gun wherever he went.

'I didn't see him shoot anyone and theoretically he could have been a member of the public or staff who just picked up a gun from a dead police officer but his behaviour wasn't what I would have expected if that was the case.'

Both believe they saw the body of the gunman after the shooting had stopped.

Mr Johnson told the BBC: 'When we were coming back in to the hotel we'd in fact seen a guy who was dead under a sheet with red shorts on who was a native of that country.

'We put two and two together and I think we got it right....there was a second gunman.'

Miss Murray, who was at the Hotel Marhaba pool with fiancé Radley Ruszkiewicz, 29, when the shooting began, says her injuries were from a small-calibre weapon and not Rezgui’s AK-47.

But the nursery nurse, of Braintree, in Essex, was not injured on the beach, but in the hotel.

Speaking from the hospital where she is being treated, Mr Murray said: ‘She was swimming in the pool and she said she heard people shooting. She was with Radley and they started running toward the hotel.

‘They both ran down the same corridor and then a grenade went off in a really confined space.

'Radley got most of the blast in his legs, and she only got a bit of it so she kept running. And further down she ended up at a dead-end and that’s when he shot her in the legs, at close range. And then he went along shooting other people in the head and legs.

‘He was shooting women in the legs and men in the head – and he stepped back over her a couple of times but she played dead.'

He said his daughter and Mr Ruszkiewicz feared each other was dead when they were taken to different hospitals. They have now been reunited and are recovering at the Cliniques Les Oliviers in Sousse.
