Police have a warrant for a second suspect as they investigate verbal threats of violence against Danbury and Stratford schools.
Days after police arrested an 18-year-old Torrington woman, police said they have obtained a warrant for a 19-year-old Torrington man.
Police have not released his name and said he is receiving medical care at a secure facility.
The warrant is for charges including first-degree conspiracy to commit assault, and criminal attempt to commit assault in the first degree.
Police have made arrangements with the health care facility to take him into custody immediately upon his release.
On Tuesday, police arrested Natalie A. Carpenter, of Main Street in Torrington.
Torrington school officials said Carpenter had a manifesto in her home describing her intentions and tried to buy guns days before the threats were made.
Officials in Danbury and Stratford were notified of the threats on Monday, police said. No threats were made against Torrington schools.
Danbury Mayor Mark Boughton said Danbury High School and Stratford's Bunnell High School received threats. No specific students were targeted. The towns have stepped up security at both high schools and parents have been notified.
Police said no additional arrests are expected.
Stratford police said there is no threat or imminent danger to students in Stratford students or schools.
