“Then 30 seconds later there was another scream. She must have screamed seven or eight times.

"The screams must have gone on for about 15 minutes.

“They sounded eerie, they sounded dark. Then I saw a male running.”

This latest revelation comes after another neighbour reported hearing "blood-curdling screams" and a gate slam at the same time Libby went missing at 12.30am last Friday morning.

She heard "other voices muttering and then more screams" before the "slamming of a wooden door or gate".

Officers arrested butcher Relowicz, 24, after swooping on his property at 9pm on Wednesday.

His home was sealed off and a silver Vauxhall Astra — believed to belong to him — had been towed away.

Forensics experts spent all day at the rented two-bed terraced home in Hull, East Yorks.

Evidence bags were removed by plain-clothes detectives.

Dad-of-two Relowicz lives with wife Jagoda less than a mile from where Libby was last seen over a week ago.

Officers insisted they were still treating her disappearance as a missing persons inquiry.

Local residents said a police helicopter had been hovering above the street for hours in the afternoon before cops descended on Relowicz’s home.

The gym enthusiast and martial arts fan, works alongside 14 other people on his production line at a meat processing factory.

He is one of around 40 Polish workers in the 150-strong department.

Colleague Tadeusz Skibicki, 39, said: “When I heard the news it was a big shock.

“Pawel is a quiet, normal person. He has never been violent.”

Relowicz has worked at Karro Food Group’s headquarters in Malton, North Yorks, for around five years, according to the pal.

Jagoda, also works there — although she has been on maternity leave after giving birth to their second child in October.

Members of Relowicz’s family in Poland told The Sun of their shock at news of his arrest. His sister Paulina Szymanska, 28, said: “I can’t believe it and I hope it’s a bad dream.

I can’t believe it and I hope it’s a bad dream.

“We come from big, poor, but wonderful family. Our parents raised us to be good, hard-working people.

“He could never do such a thing. I really hope police will find this poor girl and that it’s a big misunderstanding.”

Relowicz, from Chełmzaż near Torunń in northern Poland, married Jagoda last June.

His mum Marzena said of Pawel: “He was a good, quiet guy, helping around the house. He never caused any trouble.”

A family source told The Sun: “He was always quiet and never really had any male friends — but there were always women in his life. He is the kind of man that will do anything for his woman and would never betray or hurt her.”

Libby, a philosophy and religion student at the University of Hull vanished shortly after midnight on Friday, February 1.

She had been turned away from The Welly Club in the city for being too drunk.

Pals put her in a taxi and Libby was dropped off at her front door.

She was seen staggering around and falling over.

The last confirmed sighting was CCTV footage of her on a park bench at 11.45pm.

A neighbour told police she heard a woman’s “blood-curdling” screams. Cops can hold Relowicz for up to 24 hours but can apply to magistrates to extend it to up to 96 hours.

Libby’s parents, Lisa, 48, and Russ, 53, are being kept informed.

Karro Food Group said: “This is an active police investigation and as such it would be inappropriate to comment.”
