The man accused of going on a rape spree within an hour in the greater downtown Boston area is being fired, officials say, as the state agency he worked for investigates any other possible sexual assaults.

Solomon Wambui, 25, of Lowell is being held behind bars until February on a charge of rape and attempted rape. Police say he terrorized two women in the pre-dawn a weekend ago and was caught with his zipper down during the second alleged attack.

As the Herald first reported, he is a part-time employee of the Department of Developmental Services with an annual base pay of $39,745 and earned a total of $68,454.61 through last year.

But the Healey administration says he won’t be on the taxpayer dime for long.

“The Commonwealth has a zero-tolerance policy for sexual assault. DDS has immediately initiated the procedures required for termination. We are committed to ensuring the safety of our clients and staff,” a spokesperson for the department said Monday in a statement.

DDS, according to its website, “provides support for individuals with intellectual and developmental disabilities including Autism Spectrum Disorder to enhance opportunities to become fully engaged members of their community.”

Wambui has been a part-time employee of DDS since 2019 and the agency has contacted staff members who worked with him as DDS keeps investigating — with the Disabled Persons Protection Commission (DPPC) Sexual Assault Response Unit called in to assist.

The Herald has learned there are no allegations, to date, of abuse by Wambui logged with DDS.

The Suffolk DA’s office said they continue to move ahead with this rape case investigation and the case remains open.

Additionally, the Herald has learned that Wambui is a “recently naturalized U.S. citizen.” His home country has not been listed.

Police arrested Wambui sometime before 6 a.m. in the 200-block of Tremont Street on Oct. 26, not far from Eliot Norton Park where his second alleged victim that early morning told police she first “became aware of a male behind her” who then came at her like “he was on a mission, like a dog coming to get you.”

The victim told police he caught up to her, grabbed her by the waist, put a hand over her mouth and groped her under her skirt as she contorted herself against the assault.

Police noted in their report that as they approached Wambui and his alleged victim, “officers observed the SUSPECT’S pants to be unzipped.”

Police were already canvassing the area for a suspect, identifiable by his “small build” and short-sleeved “tan Hawaiian shirt,” of a forcible rape less than a half-mile walk away in front of a residential address in the first block of Cortes Street in the Bay Village area.

The alleged victim in that horrific encounter said that she was on the phone with her mother as she walked at around 4:30 a.m. to get back to her car after dropping a friend off in Bay Village when the man police say is Wambui approached her and wouldn’t leave her alone.

He followed her against her protests that he “go away,” she told police, until around they were on Cortes Street when he allegedly “grabbed her from the front of her neck and then from behind dragging her down to the ground,” according to the report, and forcibly raped her.
