A Douglas County teacher was fired and arrested this week after being accused of using his cell phone inappropriately.

Steve Jenkins, 54, was arrested Friday afternoon, and is being held in jail on three felonies for attempted sexual exploitation of a child, Karen Carter with the City of Castle Rock said.

What exactly Jenkins was doing with his cellphone is unclear, but a criminal investigation into the alleged misconduct is ongoing.

Jenkins worked at Renaissance Secondary School in Castle Rock since it opened its doors earlier this year.

Before that, he worked as a math teacher at Castle View High School for three years between August 2014 and May 2017.

Both schools sent letters home to parents telling them of his arrest.

Paula Hans with the Douglas County School District, confirmed to 9NEWS that the following letter was sent home to parents at Renaissance Secondary:

Dear Renaissance Secondary School Parents,

I am reaching out to share news regarding one of our staff members. As you know, Steve Jenkins joined us when we opened our doors this year as our Facilitator of Innovation.

It was brought to my attention that Mr. Jenkins was using his cell phone inappropriately. I immediately conducted an internal investigation and then reached out to the Castle Rock Police Department (CRPD). They quickly responded and are partnering with us through this process.

Please know Mr. Jenkins is no longer a member of the Renaissance Secondary School family.

I am incredibly sad to share this news. We are in the process of contacting the parents of the students whom we believe were impacted by Mr. Jenkins' activities and have support in place for the victims.

This is an ongoing, criminal investigation. All of us must respect the process as CRPD works through this situation.

I want to assure you that the Douglas County School District, and the board and administration of our school take this matter very seriously. Student safety is our top concern at Renaissance Secondary School. Thank you for your partnership.

Sincerely,

Debbie Rabideau
Leader of Learning//Principal
Renaissance Secondary School

Here's a copy of what parents at Castle View High School were sent:

Dear Castle View High School Community,

Tonight, I am reaching out to share some news about a former CVHS staff member. As you know, Steve Jenkins was a member of the Castle View faculty as recently as last year, until he took a position with Renaissance Secondary School.

We have learned that Mr. Jenkins is being investigated by the Castle Rock Police Department (CRPD) for using his cell phone inappropriately. Mr. Jenkins is no longer a staff member at Renaissance Secondary School.

At this time, we have not been notified of any connection between this investigation and CVHS. However, given that Mr. Jenkins was recently a member of our staff, I felt it was important to share this information with you.

Because this is an ongoing, criminal investigation, I do not have any further information. If you have any concerns that may be tied to this investigation, I encourage you to reach out to the Castle Rock Police Department.

As always, I am available should you have any questions. Thank you for your partnership and I look forward to seeing all of our students and staff back at CVHS on Monday!

Sincerely,
Dr. Rex Corr
Principal
Castle View High School

The Castle Rock Police Department is handling the investigation.
