A builder who died after falling from the third floor of the Bullring had claimed he was being followed, an inquest heard.
Lithuanian-born Donatas Giedrys, aged 34, fell 50ft in front of horrified shoppers on the evening of June 29 last year.
But assistant deputy coroner Sarah Ormond-Walshe said there were no suspicious circumstances and no-one else was involved in his death.
She recorded that he took his own life.
The inquest heard Mr Giedrys visited his boss on the day of his death with two police officers in tow.
The court heard Mr Giedrys claimed he had been followed by an unknown man and did not want to return to his own flat.
Following negotiations, the inquest heard he was given £100 and arrangements were made for him to return to Lithuania and stay in a hotel for two nights.
Witness Simon O’Sullivan, who saw Mr Giedrys fall, said: “He rushed up to the barrier and sort of zig-zagged through various members of the public.
“I looked at him as he ran towards the barrier. He had a euphoric look on his face.
“There was no hesitation. He just put both hands on the barrier and vaulted over.
“He fell feet first. It was like someone jumping into a swimming pool. He crashed to the floor.”
Security guard Matthew Jones said: “When I looked up he was in mid-air. He was clear of the balustrade.
“There was no-one within reasonable distance of him.”
The inquest heard that Mr Giedrys, of Bordesley Green Road, Small Heath, was treated by paramedics before being taken to the Queen Elizabeth Hospital, where he died from multiple injuries.
The coroner said it did not appear that Mr Giedrys had any mental health problems.
“When someone jumps from that height one would not expect to live,” Ms Ormond-Walshe said.
