Bermuda's hospital early yesterday.

It follows last month's chemical attack on hospital staff which sparked a security alert.

An extra security officer is now on duty at the emergency department. And just two patients can visit patients.

Today an investigation is being launched into the latest disturbance.

Trouble stemmed from an attack on a 22-year-old Warwick man in Dundonald Street.

Police rushed to the scene at about 3.30 a.m. yesterday.

A large crowd surrounded the victim who lay semi-conscious in a pool of blood.

He was treated at King Edward VII Memorial Hospital.

"Further trouble apparently flared up when several people from the scene arrived at the hospital and tried to gain admission,'' said Police spokesman P.c. Gary Venning.

"Details are limited at this time but the incident is under investigation.'' P.c. Venning added a 27-year-old Devonshire man was helping with inquiries.

The flare-up comes just three weeks after a woman doctor, patient and Policeman were terrorised during an assault at the hospital.

They had a chemical sprayed in their faces.

Just hours earlier a nurse was injured by a patient in a separate incident.

Yesterday Dr. Edward Schultz, director of emergency services at King Edward, said he would be looking into the disturbance.

"I cannot really comment. We have been extremely busy, and I have not been advised about any incident. I will check it out.'' Dr. Schultz said unruly behaviour in the emergency department was common these days.

"It is not uncommon for Police to be called to the unit.'' Last month's incident brought on plans to beef up security dramatically, and restrict access to the department.

Dr. Schultz said only some of the proposed security measures were now in place.

An extra security officer was questioning people entering the department.

"We also have a log for people entering it,'' said Dr. Schultz.

He added: "There are also restrictions on the number of visitors allowed to see patients.'' Dr. Schultz said he had been in touch with Police over security.

"The measures are going to take a little bit longer than expected,'' he said.
