Thea Walker’s family has been moved by the support they have received from the public after the young girl lost her Holy Communion dress following a building collapse in Guardamangia.

The seven-year-old girl was one of the two children who had to evacuate their homes as the wall of the building they were living in collapsed.

Following the incident, the seven-year-old girl’s aunt told reporters her Holy Communion dress was inside the building, which was still unsafe to enter.

But Janet Walker said she had been moved by the dozens of messages she received offering her niece another Holy Communion dress for the ceremony on Sunday.

"We are very grateful," she said. "It is in these moments you really realise how much the Maltese help each other".

"People messaged on Facebook and a few shops offered my niece a Holy Communion dress as well," she said.

The family is staying at a hotel until alternative accommodation is provided. The local council has come forward to help, although mayor Kevin Tanti has said the situation was "still very fluid".

Although Ms Walker was still angry at authorities and the contractor, she said she was moved by how many people came forward and offered to help.

“Everyone is worried it will be their turn tomorrow, since the whole country is under construction,” she said. "People are coming forward to help because they are worried they will be next," she added.

The family was earlier on Thursday trapped outside their house with nothing but the clothes on their back. They could not even buy food to eat since they ran out of the house with no cash, and were stranded outside in the sweltering heat.

The young girl went to stay at a friend’s house until accommodation was sorted, and in spite of her shock, she tried to lighten the situation by joking with her mum.

"We had gone on holiday recently, so she quickly told her mum: this is no problem, we’ll just go on holiday again until the place is fixed up," Ms Walker said.
