Members of the City Constabulary have recovered three busts that were removed from the Non-Aligned Monument at Company Path Garden, Avenue of the Republic on Thursday.
The perpetrator, who is believed to be a man of unsound mind, has been detained.
A press release from Government Information Agency (GINA) said the sculptures were in the possession of the City Council and will be restored to their original positions with the aid of the National Trust.
The Chief Constable and the Town Clerk are considering raising the fence surrounding the Garden to prevent easy access by vagrants.
The monument commemorates the 1972 Conference of Foreign Ministers of Non-Aligned countries, which was held in Guyana in August that year.
It was symbolically unveiled by Arthur Chung, the first president of Guyana, in honour of the founders of the Non-Aligned Movement: presidents Gamal Abdel Nasser of Egypt, Kwame Nkrumah of Ghana, Pandit Jawaharlal Nehru of India and Josip Broz Tito of Yugoslavia.
According to the GINA release, the problem of vagrancy has for years engaged the attention of the ministries of Health, Home Affairs and Human Services and Social Security and a $400 million facility is in the pipeline for the establishment of a home for the homeless.
The Ministry of Heath will be embarking on a campaign to remove vagrants from the street, carrying out medical evaluations and ensuring that they do not return.
Treatment for these persons will be provided at the Medical Clinic of the Georgetown Hospital or the National Psychiatric Hospital.
The release said now that the Human Services Ministry has expanded the services at the Night Shelter to 24 hours a day, the Ministry of Health will be referring patients there on a regular basis.
A National Mental Health Strategy, which has been in the making for some time, will address mental health issues such as substance abuse, depression and eating disorders among others.
