In the wake of the shooting at a Catholic school in Minneapolis on Wednesday, Connecticut schools are increasing their police presence at districts across the state.

Officers are taking the initiative despite there being no active threats to any Connecticut schools or places of worship.

"It's really sad that we have to have this conversation on the first day school," said New Haven Mayor Justin Elicker.

Elicker and New Haven Superintendent, Dr. Madeline Negrón, spoke with reporters while visiting students on their first day of school at Lincoln Bassett on Thursday.

"It is sad that in this amazing nation that we are in, that that is what we have to be worrying about instead of thinking about preparing right to support our kids academically," Dr. Negrón said.

Throughout the state, school districts like Berlin, Cheshire, Colchester and Middletown are putting an extra police presence at schools and places of worship this week.

Middletown's mayor and police chief took to social media, saying in part, "We are deeply saddened by this continuation of senseless violence in our country. Please know that we are committed to doing everything in our power to prevent such tragedies here at home."

In New Haven, Dr. Negrón said school security is always top of mind.

"Here it's about continuing to practice the procedures that we have, the protocols that we have, the amazing security staff that we have," Dr. Negrón said.

Mayor Elicker said the district has 10 school resource officers, metal detectors in the high schools and each building is locked and secured.

In addition, he said all police officers are trained in active shooter situations in schools, and each building is regularly checked to make sure they're secure.

"The security is very strong in the schools. It's difficult to get into our schools," Elicker said.

However, Elicker knows that despite preparing for any situation, he also knows school shootings can happen anywhere.

"I just, it's every parent's worst nightmare. It's my worst nightmare as mayor. And I'm sure Dr. Negrón shares this feeling that, this type of incident would happen in New Haven and, and it's happening all too often in our nation," Elicker said.

"My heart goes out. My prayers go out to the whole community. Yesterday, Minnesota, that had to experience, such a tragedy," Dr. Negrón said.
