A 10-year-old boy at a holiday park was mauled to death by a dog early Saturday morning, police say.
Despite the efforts of emergency services, the boy was pronounced dead at the scene.
"Following this incident, searches were undertaken to locate the dog and its owner," the Devon and Cornwall police said in a statement.
Officers launched a search for the dog, described as a "bulldog-type" breed.
Shortly after 8 a.m., police arrested a 28-year-old woman in Saltash on suspicions of manslaughter and of "having a dog dangerously out of control."
Police were also able to locate the dog, which has since been transferred to kennels.
The 10-year-old boy's family are aware of the incident and are being supported by the officers, police said.
The witness added, "The park is effectively in lock down and we have heard there has been a fatality. It is so sad to hear a child is involved. Just awful."
Meanwhile, Holiday Park manager Robert Ellwood said police hadn't alerted him to any information about the incident.
Councillor Armand Toms, the mayor of Looe, spoke about the tragedy.
"This latest tragedy is so sad for the family. Our thoughts are with them at this time," he said, according to Mirror.
"This community will do whatever it can to help. It always has done and will in the future and I am speaking not as the town's mayor but as someone born and bred here," he added.
He also spoke about other child tragedies to hit the town.
"It's very sad. We have been through a pretty tough time. Just last year Maisie Duncan, a 7-year-old girl, was killed when she was struck by a car which lost control in the snow and hit her as she played on the pavement," he said.
"It's been so sad because we have just had the anniversary of Maisie's death and the court case that followed."
He also went into the history of the holiday park.
"Tencreek holiday park has been there for many years. It is run by a guy who is connected to our music festival," he said.
"It is very well established and has probably been around for 40 years. Some local youngsters go up there to use the swimming pool in the winter and learn how to swim," he said. "It is part of our community and has been for a long time."
