More students were arrested in Isla Vista and on the UC Santa Barbara campus in April than in any of the past six months, according to data from the Nexus’ arrest log.

57 people were arrested in I.V. or UCSB in September 2018, the next-highest month included in the arrest map.

More April arrests occurred in I.V. than on the UCSB campus. Only 18 of the arrests occurred on the UCSB campus, while 56 arrests occurred in Isla Vista in the same period of time. It is unclear whether two arrests occurred in Isla Vista or on campus.

Nearly twice as many individuals were arrested in April than March. In April, 76 individuals were arrested, compared to 39 individuals in March. This can likely be attributed to the unsanctioned street party known as Deltopia, which happens yearly during the first week of spring quarter.

This year, Deltopia happened on April 6; 38 arrests in the month occurred on that date, making up half of the total number in April. Another arrest occurred at 12:38 a.m. on April 7.

This was a 50% increase from the previous year’s Deltopia.

Over one-fourth of arrested individuals on Deltopia were confirmed UCSB students. For the rest of the month, about 30% of arrests were UCSB students.

The oldest person arrested during Deltopia was 27. Over 90% of individuals arrested in I.V. during Deltopia were under 22.

Approximately one-third of other arrests in April were of individuals 27 or older.

Over half of the arrests in April were related to alcohol, similarly to previous months. Disorderly conduct due to alcohol was again the most common charge in April, with 39 people charged; 30 of these occurred during Deltopia.

Violation of probation, criminal conspiracy and vandalism were other common charges.

Six individuals were arrested for violating their probations. Five were charged with criminal conspiracy, and another five were charged with vandalism.

Four individuals were charged with obstructing or resisting a police officer. Four were charged with possession of unlawful paraphernalia, which is equipment that is used to consume, process or store illegal substances.  

The arrest map is based on daily arrest logs from the Santa Barbara County Sheriff’s Office and includes arrests that happen in I.V. as well as on the UCSB campus. The map includes data through September 2018 to the present.
