Tenants in a Nottinghamshire sheltered housing complex say they have fears for their safety as a result of anti-social behaviour.
On Monday, firefighters evacuated Walton Court on Cavendish Road, Carlton, after rubbish was deliberately set alight in a stairwell.
Incidents previously reported, include tenants having their locks glued and cases of arson, police said.
A "closer eye" is being kept on the building, they added.
One resident, who did not want to be named, said lights in the communal areas had not been working for a month.
"A few months ago, the fires were outside but now they are moving inside," said the Walton Court resident. "Some say it's only a matter of time before someone gets killed."
Gedling Homes, which owns the property, said concerns were being addressed.
In a statement, it said: "We have visited tenants at Walton Court to reassure them and address their concerns.
"Temporary lighting has now been provided and the smoke-damaged stairwell made safe to use in emergencies while a full refurbishment is carried out.
"Gedling Homes is reviewing security arrangements at Walton Court and a number of enhancements have already been implemented."
