Refugee rights activists now say staff have been warned that the attacker is dangerous.
Among the seriously injured was PC policeman David Whyte, who was taken to hospital in critical condition.
Ako Zada, a refugee rights activist, said that many asylum seekers had been transferred to hotels and that all the money spent had been taken from them, reports the Daily Record.
They all received three bad standard meals a day, said Zada.
The “dehumanizing” and “humiliating” conditions have left some residents depressed, he added.
And he said he heard from those staying in the 91-room hotel that a resident had threatened serious violence against reception staff.
Zada, of the Kurdish and Scottish liaison group Zados, said: “I was told that the hotel had been warned that a man had been pushed overboard and posed a great danger to the staff.
“I didn’t get confirmation that the hotel knew, but that’s what I was told.
“We were aware of very high tensions during the lockdown and many people suffer from mental health issues because of this.”
Positive Action in Housing criticized private housing provider Mears Group, which is contracted out by the Home Office, for moving refugees from self-contained accommodation to hotels during the foreclosure.
And Mr. Zada said, “Mears claims it was sort of to make it safer for people, but I don’t know how you can go from a small apartment to a large hotel with over 100 residents and it’s safer.
“I believe at least 300 and possibly 500 have been displaced recently. The reports we have received have focused on poor standard food and there have been refusals to eat the food in the past few weeks.
“When people were transferred to hotels, all the money was taken from them. It’s dehumanizing. It’s humiliating.
“The tension of isolation and the lack of proper social distancing will all take its toll.
“The hotels are overcrowded and this will certainly lead to depression.
“It’s okay to live in a hotel for a few weeks but not for months.
“People were forced to share the toilet. We have made complaints to the Scottish Refugee Council and the Scottish government, but things have gotten worse, not better. ”
Last month, the Mears group issued a statement after the death of a hotel resident in a suspected drug overdose.
He said the hotels were used for containment “to create a safe environment to significantly reduce the spread of Covid-19 among asylum seekers in Glasgow”.
Nicola Sturgeon spoke yesterday of the tensions that surfaced in George Square in Glasgow amid protests against the living conditions of the refugees.
At least six people were arrested on June 17 after far-right thugs targeted the rally.
Asked how the hotel was used to house asylum seekers, Sturgeon said: “There has clearly been tension in Glasgow as there has been in other parts of the UK in recent times. .
“But I want to send a message to the people of Glasgow and Scotland – when terrible things like this happen, they should remind us of what unites us, not what divides us. ”
Mears said last night that he was referring all requests to the Home Office “because this is an ongoing police operation.”
An Interior Ministry spokesperson said, “We are aware of an incident on West George Street in Glasgow which is currently under investigation by the police. ”
The group later released a statement that said, “The Mears group is deeply saddened and shocked by the tragic events that have taken place in the heart of Glasgow today. The Home Office has given us a contract to provide accommodation and support services for asylum seekers in Scotland.
“We are not planning a live police investigation, but we can confirm that the attack took place in a hotel where we are hosting asylum seekers during the period of isolation.
“We will provide more details as far as we can and our priority is to ensure the well-being of our service users who will no doubt be traumatized by this terrible event.
“Tonight, we are also thinking of the hotel staff and our colleagues on site – all are on our mind. “
